title: Proper server response for Backbone.js
body: <p>I am implementing Backbone.js with Codeigniter, and having a hard time receiving a proper response from Codeigniter upon a Ajax call. I was doing a #Create, which led to #save, and then #set, right at there, it breaks and couldn't find the ID in the format I returned the data.</p>
  
  <p>For testing purpose, I'm echo-ing </p>
  
  <pre><code>    '[{"id":"100"}]'
  </code></pre>
  
  <p>right back to the browswer, still it couldn't find it.</p>
  
  <p>Anyone aware of a Backbone/Codeigniter(or similar) RESTful implementation example?</p>
