title: Backbone.js fetch callback
body: <p>I'm using Backbone.js and using fetch with options, but it doesn't seem to get the error or success callbacks, however data is being returned.</p>
  
  <pre><code>this.user.fetch({data: {username : this.username.val(), check : 'true'}}, {
      error: function(model, response) {
          console.log(response);
      },
      success: function(model, response)  {
          console.log(response);
      }
  });
  </code></pre>
  
  <p>This is what I have setup, am I missing something? It never hits error or success, but it does do the ajax request and it's returning data.</p>
  
  <p>Thank you!</p>
