Backbone.js-集合未定义

我正在尝试学习backbone.js，但我一直在获取json并添加到集合中。该集合未定义，我不知道为什么。代码：

$(document).ready(function() {
    (function($) {
        //model
        window.Wine = Backbone.Model.extend();
        window.WineCollection = Backbone.Model.extend({
            url: "http://localhost/bootstrap/json.php",
            model: Wine
        });

        //views
        window.WineItemView = Backbone.View.extend({
            template: _.template($("#wine-item-template").html()),
            tagName: 'li',
            render: function() {
                $(this.el).html(this.template(this.model.toJSON()));
                return this;
            }
        });
        window.WineListView = Backbone.View.extend({
            tagName: 'ul',
            initialize: function() {
                this.model.bind('reset', this.render, this);
            },
            render: function() {
                _.each(this.model.models, function(wine) {
                    $(this.el).append(new WineItemView({
                        model: wine
                    }).render().el);
                }, this);
                return this;
            }
        });

        window.WineView = Backbone.View.extend({
            template: _.template($('#wine-template').html()),
            render: function() {
                $(this.el).html(this.template(this.model.toJSON()));
                return this;
            }
        });
        //Router
        window.AppRouter = Backbone.Router.extend({
            routes: {
                '': 'home',
                'wines/:id': "wineDetails"
            },
            home: function() {
                this.wineList = new WineCollection();
                this.wineListV = new WineListView({
                    model: this.wineList
                });
                this.wineList.fetch({success: function(){
                    console.log(this.wineList.models); // => 2 (collection have been populated)
                }});
                console.log(this.wineListV);
                $("#winelist").html(this.wineListV.render().el);
            },
            wineDetails: function(id) {
                this.wine = this.wineList.get(id);
                console.log(id);
                this.wineView = new WineView({
                    model: this.wine
                });
                $("#container").empty().html(this.wineView.render().el);
            }
        });

    })(jQuery);
    var app = new AppRouter();
    Backbone.history.start();
});

json.php返回：

[
   {
      "name":"Wine 1",
      "price":"100",
      "status":"available"
   },
   {
      "name":"Wine 1",
      "price":"100",
      "status":"available"
   },
   {
      "name":"Wine 1",
      "price":"100",
      "status":"available"
   }
]

我正在本地主机上测试它。
