Extremely simple error with backbone.js throwing invalid object initializer error
===

Okay, I try to avoid posting silly questions, but I can't figure out this error and if it's this subtle it may help other people anyway.

What is wrong with this code:


    (function($){
    
    
    var Item=Backbone.Model.extend({
      defaults: {
        ItemName:'Item ',
        counter:0,
        index:0,
        allSetView:'',
        Set: []
      },
      initialize: function(){
      alert('youve created a new item');
      }
    });
    
    var item=new Item();
    alert(item.get({"index"}));//error thrown here
    })(jQuery);
