title: jQuery ajaxStart works only on the first request
body: <p>There is a page on which a lot of requests ajax. When performing queries I want to display a block with the text "Loading".</p>
  
  <pre><code>$(document).ajaxStart(function() {
              $( "#loader" ).show();
          });
      $(document).ajaxStop(function(){
              $( "#loader" ).hide();
          });
  </code></pre>
  
  <p>But it works only on the first request.</p>
