BackBone首次点击不起作用

Question

首次点击元素时，事件不起作用，第二次点击按预期工作

命名空间：

var goose = goose || {
    Models: {},
    Views: {},
    Collections: {},
    Routes: {}
};

集合，我在其中使用过滤器进行数据处理：

goose.Collections.CollectionChannels = Backbone.Collection.extend({
    model: goose.Models.ModelChannel,
    localStorage: new Backbone.LocalStorage("Channels"),
    fetch: function(options) {
        // check if localStorage for this collection exists
        if(!localStorage.getItem("Channels")) {
            var self = this;
            // fetch from server once
            $.ajax({
                url: 'json/channels.json'
            }).done(function(response) {
                $.each(response, function(i, item) {
                    self.create(item);  // saves model to local storage
                });
            });
        } else {
            // call original fetch method
            return Backbone.Collection.prototype.fetch.call(this, options);
        }
    },
    byFilter: function(filter, value) {
        var _this = this, f;
        this.fetch({success: function() {
            f = _this.filter(function(model) {
                return model.get(filter) == value;
            }); 
        }, 
        error: 
            function() {
                alert("Ошибка, обновите страницу.");
            }
        });
        return new goose.Collections.CollectionChannels(f);
    }
});

查看，设置活动：

goose.Views.ViewСhannel = Backbone.View.extend({
    id: "item",
    template: _.template($("#news_item").html()),
    initialize: function() {
        this.listenTo(this.model, "change", this.render);
        this.render();
    },
    render: function() {
        this.$el.html(this.template(this.model.toJSON()));
        return this;
    },
   events: {
       "click .favor" : "addToFavor"
   },
   addToFavor: function() {
       this.model.set("favorite", !this.model.get("favorite"));
       this.model.save();
   }
});

初始化视图并在过滤后添加集合：

goose.Views.viewСhannels = new goose.Views.ViewСhannels({
     collection: goose.Collections.collectionchannels.byFilter("cat", "news"),
     el: ".news .content"
});
