title: Backbone Fetch triggers success but returns zero length
body: <p>I am new to Backbone. Pardon me if this has been answered before. I tried googling but couldn't reach a solution.</p>
  
  <pre><code>window.InfoCollection = Backbone.Collection.extend({
      model:InfoModel,
      url:"../api/info",
        parse: function (response) {
          console.log("In Parse" + response.length)
          return response;
      }
  });
  </code></pre>
  
  <p>Here this returns the length correctly as 1</p>
  
  <p>However it shows up as 0 here.</p>
  
  <pre><code>    this.InfoCollection.fetch({success:function(){console.log(this.length)}});
  </code></pre>
  
  <p>Consequently when I initiate a view with the InfoModel, it fails.</p>
  
  <p>Can any expert please point me in the right direction?</p>
