title: jsonpCallback function not working
body: <p><strong>UPDATE 1:</strong></p>
  
  <p>I've just upgraded from jquery 1.4.4 to 1.6.1.  How does that effect the script in the original question?</p>
  
  <p><strong>ORIGINAL QUESTION:</strong></p>
  
  <p>Just as I test, I did:</p>
  
  <pre><code>$(document).ready(function() {
      get_jsonp_feed();
  
      function get_jsonp_feed() {
          $.ajax({
              url: 'http://www.remote_host.co.uk/feed.php',
              type: 'GET',
              dataType: 'jsonp',
              jsonp: 'callback',
              jsonpCallback: 'jsonpCallback',
              error: function(xhr, status, error) {
                  alert("error");
              },
              success: function(jsonp) { 
                  alert("success");
              }
          });
      }
  
      function jsonpCallback(data){
          alert("jsonpCallback");
      }
  });
  </code></pre>
  
  <p>I was expecting to get 2 alerts, the first showing <code>success</code> and the second showing <code>jsonpCallback</code>.  But I am only getting the first alert <code>success</code>.  Why is the second alert not showing up?</p>
