Backbone.js - 名称更改时未触发更改

在我的骨干函数中，虽然名称发生更改，但更改函数根本不会触发..任何人都建议我获得它的正确方法..（实际上我需要更改内容并需要更新）；

code :

    (function($){

var list = {};

list.model = Backbone.Model.extend({
  defaults:{
    name:'need the name'
  },
  initialize:function(){
    this.bind('change:name', function(model) {
        console.log('Model->change()', model);
    });
  }
});

list.collect = Backbone.Collection.extend({
  model:list.model,
  url : 'data/names.json',
  initialize:function(){
    this.fetch({update:true});
    this.keepUpdate();
  },
  keepUpdate:function(){
    var that = this;
    var updateData = function(){
      that.fetch({update:true});
      myTimeout = setTimeout(updateData,10000);
    }
    var myTimeout = setTimeout(updateData,10000);
  }
});


list.view = Backbone.View.extend({
  initialize:function(){
    this.collection = new list.collect();
    this.collection.on("update", this.render, this);
    this.collection.bind("change:name", function(model, attributes){
      console.log(model,attributes,'property changed'); // this is not triggering at all..
    });
  },
  render:function(data){
    _.each(this.collection.models, function(data){
      //console.log(data.get('name')); it works fine
    })
  },
  updateName:function(){
    console.log('updated called');
  }
});

var newView = new list.view();    

})(jQuery)

Collection.fetch 不会触发change事件。你只得到reset事件。如果您需要更精细的事件，请考虑致电fetch http://backbonejs.org/#Collection-fetch与选项{update:true}.

that.fetch({update:true});

这会触发change该系列中已有的每个模型的活动，以及add如果该模型以前不在集合中。
