为什么Backbone.Modelbinder只绑定视图列表的最后一个实例

Question

In a list of items, every item has its' own modelbinder object to bind the models' values.

The problem that I'm having could be reproduced: http://jsfiddle.net/goodafternoon/NmgkY/#base

Only the last element that appears in the list gets bound and thus only the that element responds to the models event listener

this.on("change", function() {
    console.log('event');
});

I'm using ironcooks famous Modelbinder module : https://github.com/theironcook/Backbone.ModelBinder

Fixed it.

If you had a similar problem, here is the updated fiddle: http://jsfiddle.net/goodafternoon/XwT2k/1/

The problem was that I was creating a new instance of the ModelBinder object in the class rather than creating it when the model is instantiated, so there was only ever one ModelBinder, which is why I only ever got the binding on one element.
