Some feedback on a Javascript MVC app that uses functional inheritance

I'm looking for some feedback on my implementation of MVC and functional inheritance (as described by Douglas Crockford in his book 'The Good Parts') in an app that uses the YouTube API.

This is my first time building anything remotely object-oriented so I'd really appreciate some advice on this app.

You can view the app in full here. Here are some relevant code snippets:

Model:

models.YTData = function(data) {
    var feed = data.feed,
        entries = feed.entry,
        length = entries.length,
        newData = {vids: []};

        for(var i = 0; i < length; i+=1) {
            var index = (i + 1) % 5,
                entry = entries[i],
                date = entry.published.$t,
                jsDate = new Date(date.substring(0, 4), date.substring(5, 7) - 1, date.substring(8, 10)),
                todayDate = new Date(),
                oneDay = 1000 * 60 * 60 * 24,
                views = entry.yt$statistics.viewCount,
                numOfDays = Math.ceil((todayDate.getTime() - jsDate.getTime()) / oneDay);

            if (entry.media$group.media$content !== undefined) {
                newData.vids.push({
                    title: entry.title.$t,
                    url:  entry.media$group.media$content[0].url,
                    index: index === 0 ? index + 5 : (i + 1) % 5,
                    views: controllers.addCommas('' + views),
                    date: '' + jsDate.getUTCDate() + ' ' + controllers.utilFunctions(jsDate.getMonth()).convertMonth() + ' ' + jsDate.getFullYear(),
                    average: controllers.addCommas('' + Math.round(views / numOfDays))
                });
            }

            else {
                continue;
            }
        }
    localStorage.vids = JSON.stringify(newData);
    return newData;
};

Controller:

controllers.request = function(obj) {
                var obj = obj || {};
                var that = {
                    base_url: 'https://gdata.youtube.com/feeds/api/standardfeeds',
                    max_results: 25,
                    start_index: obj.start_index || 1,
                    alt: 'alt=json-in-script',
                    country: obj.country ? '/' + obj.country : '',
                    genre: obj.genre ? '&category=' + obj.genre : '',
                    call_url: function() {
                        return that.base_url + that.country + '/on_the_web_Music' + '?max-results=' + 
                              that.max_results + '&start-index=' + that.start_index + '&' + 
                              that.alt + that.genre;
                    },
                    ajax: function() {
                        views.loading();
                        $.ajax({
                            type: 'GET',
                            url: that.call_url(),
                            dataType: 'JSONP',
                            error: function() {
                                views.serverError().hide();
                            },
                            success: function(data) {
                                var loading = views.loading;
                                views.loading = function() {};
                                if (data.feed.entry === undefined) {
                                    views.noResults().hide();
                                }

                                else {
                                    views.displayFirst(models.YTData(data)).pager(obj.genre, obj.country);
                                }
                                views.loading = loading;
                            }
                        });
                    }
                };
                return that;
    };

Views (showing an example of functional inheritance):

views.display = function(data) {
    var that = {
        vids: data.vids,
        condition: data.vids.length >= 5 ? 5 : data.vids.length,
        hideCurrentVids: function() {
            $('.playerContainer').animate({opacity: 0}, 500, function() {
                that.showVids.apply(that);
            });
        },

        showVids: function() {
                $('#vids').html(views.tplVids(data)).css('opacity', '1');
                $('#loader').css('display', 'none');
                for (var i = 0; i < this.condition; i += 1) {
                    views.loadVideo(this.vids[i].url, false, i + 1);
                    $('#player' + (i + 1))
                        .parent()
                        .parent()
                        .css({position: 'relative', top: 0})
                        .delay(i * 500)
                        .animate({opacity: 1}, 1000);
                }
                $('#videos').removeData('loading');
                $('#loader').css('display', 'none');
        }

    }
    return that;
};

views.displayFirst = function(data) {
    var that = views.display(data); // inherits from views.display
    that.length = data.vids.length;
    that.pagerArray = {pagerItems: []};
    that.counter = 0;
    that.pager = function(genre, country) {
        if (this.length > 5) {
            for (var i = 0; i < this.length; i += 5) {
                this.counter += 1;
                this.pagerArray.pagerItems.push({
                    index: this.counter
                });
            }
            document.getElementById('pager').innerHTML = views.pagerGen(this.pagerArray);
            $('#pager').animate({
                opacity: 1
            }, 500);
            data.vids.splice(5);
        }

        else {
            $('#pager').empty();
        }
        this.showVids();
        views.viewing(genre, country);
    };
    return that;
};

Thanks in advance.
