Angular.js request/response Node.js

I am trying to request some data from node.js server from my angular.js. The problem is that upon data response i see a blank browser window with my json object printed on it. I want angular.js to recognize the response and stay on page.

HTML form - template that gets loaded with loginController

<section class="small-container">
    <div class="login-form">
        <form action="/login" method="post" ng-submit="processForm()">
            <input ng-model="formData.username" type="text" name="username">
            <input ng-model="formData.password" type="password" name="password">
            <button>login</button>
        </form>
    </div>
</section>

Angular.JS

var app = angular.module("blavor", ['ngRoute']);

app.config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) {
    $routeProvider
        .when("/", {
            templateUrl: "/index",
            controller: "loginController"
        })
        .when("/register", {
            templateUrl: "/register",
            controller: "registerController"
        })
        .otherwise("/");

        $locationProvider.html5Mode(true);
}]);

app.controller('loginController', function($scope, $http) {
    $scope.formData = {};
    $scope.processForm = function() {
        $http({
            method: 'POST',
            url: '/login',
            data: $.param($scope.formData),
            processData: false, 
            responseType: "json",
            headers: {
                'Content-Type': 'application/x-www-form-urlencoded'
            }
        }).success(function(data) {
                console.log(data);
                if (!data.success) {
                    alert("Noo!");
                } else {
                    alert("YEEEY!");
                }
            });
    };
});

Node.js Server - index.js

var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);
var express = require('express');

var bodyParser = require('body-parser');
app.use( bodyParser.json() );
app.use( bodyParser.urlencoded({ extended: false }) );
var routes = require('./routes')(app);
http.listen(3000, function() {
    console.log('listening on *:3000');
});

module.exports.start = start;

Node.js Server - routes

module.exports = function(app) {
app.post('/login', function(request, response) {
console.log(request.body);
    response.setHeader('Content-Type', 'application/json');
    response.end(JSON.stringify({value:"somevalue"}));
});
}

I am using AngularJS v1.2.24 and Node.js v0.10.25

console.log(data) in angular never gets called..
