Comment définir autoUpload option pour Jquery File Upload

je suis en train de définir autoUpload drapeau à jQuery File Upload.
J'ai donc essayer de modifier jquery.fileupload.js de cette façon:

(function (factory) {
    'use strict';
    if (typeof define === 'function' && define.amd) {
        //Register as an anonymous AMD module:
        define([
            'jquery',
            'jquery.ui.widget'
        ], factory);
    } else {
        //Browser globals:
        factory(window.jQuery);
    }
}(function ($) {
    'use strict';

    //The FileReader API is not actually used, but works as feature detection,
    //as e.g. Safari supports XHR file uploads via the FormData API,
    //but not non-multipart XHR file uploads:
    $.support.xhrFileUpload = !!(window.XMLHttpRequestUpload && window.FileReader);
    $.support.xhrFormDataFileUpload = !!window.FormData;

    //The fileupload widget listens for change events on file input fields defined
    //via fileInput setting and paste or drop events of the given dropZone.
    //In addition to the default jQuery Widget methods, the fileupload widget
    //exposes the "add" and "send" methods, to add or directly send files using
    //the fileupload API.
    //By default, files added via file input selection, paste, drag & drop or
    //"add" method are uploaded immediately, but it is possible to override
    //the "add" callback option to queue file uploads.
    $.widget('blueimp.fileupload', {

        options: {
            //The namespace used for event handler binding on the dropZone and
            //fileInput collections.           
            //If not set, the name of the widget ("fileupload") is used.
            namespace: undefined,
            autoUpload:true,
            .
            .
            .

et main.js de cette façon:

$(function () {
    'use strict';

    //Initialize the jQuery File Upload widget:
    $('#fileupload').fileupload();

    //Enable iframe cross-domain access via redirect option:
    $('#fileupload').fileupload(
        'option',
        'redirect',
        window.location.href.replace(
            /\/[^\/]*$/,
            '/cors/result.html?%s'
        )
    );

    if (window.location.hostname === 'blueimp.github.com') {
        //Demo settings:
        $('#fileupload').fileupload('option', {
            url: '//jquery-file-upload.appspot.com/',
            maxFileSize: 5000000,
            autoUpload:true,
            .
            .
            .

je peux voir à travers cette

<td class="start">{% if (!o.options.autoUpload) { %}
    <button class="btn btn-primary">
        <i class="icon-upload icon-white"></i>
        <span>{%=locale.fileupload.start%}</span>
    </button>
{% } %}</td>

que le bouton de démarrage s'affiche, donc o.des options.autoUpload est false, mais je l'ai mis à true.
Que puis-je faire? en ce qui me permet de autoupload télécharger l'image directement lorsqu'il est sélectionné?
merci!!!!
