title: Strange behavior backbone, javascript
body: <p>In a view I've an onClick event that call a function:</p>
  
  <pre><code> retweet: function () {
             cb.__call(
                  "statuses_retweet_ID",
                  "id=472518063737536512",
                  function (reply) {
                  //gestire rate limit error 429
                   console.log(reply);
                   return reply;
                  }
              );
        },
  </code></pre>
  
  <p>The strange behavior is: if don't click and consequently retweet function is not called my application works perfectly but if I click the function is executed but the app crash and some variable will undefined. I can't understand, maybe is the cb.__call function?</p>
