Backbone - how get this sort out… some part still not clear

in my backbone function, i am keep fetching the data using setTimout while i fetch the data, i am sending property as {add:true} so it means, the model which i am getting newly will going to add with existing collection, when the collection get the model added , it should trigger the add method.

But i am not getting the trigger on the after add process made in my collection. but i am fetching the data in view process, it is not correct.

my collection:

list.collect = Backbone.Collection.extend({
  model:list.model,
  url : 'data/names.json',
  initialize:function(){
     this.fetch({success:this.prompter});
     this.on("add", this.addOne, this);//it should get triggered while added the model
  },
  addOne:function(e){
    console.log('addone'); // the method not called
  }
});

my view :

list.view = Backbone.View.extend({
  initialize:function(){
    this.collection = new list.collect();

    var that = this;
    var updateData = function(){
      that.collection.fetch({add:true}); // i am passing add:true!
      myTimeout = setTimeout(updateData,10000)
    }
    var myTimeout = setTimeout(updateData,10000)

    this.collection.on("reset", this.render, this);

  },
  render:function(data){
    _.each(this.collection.models, function(data){
      //console.log(data.get('name'));
    })
  }
});

any idea about the issue please?
