$('#fileupload').bind('fileuploadsubmit', function (e, data) {
var inputs = data.context.find(':input');
if (inputs.filter(function () {
        return !this.value && $(this).prop('required');
    }).first().focus().length) {
    data.context.find('button').prop('disabled', false);
    return false;
}
data.formData = inputs.serializeArray();
console.log( inputs.serializeArray() );
