title: Call function to pass parameter in the DataTables reload
body: <p>I use the JQuery DataTables plugin and I initialize it with ajax parameter.</p>
  
  <p>I'll need to calcolate new parameter when I reload data but not run if I pass parameter in the function.
  I call the ajax.reload from a "Reload" button.
  Why I can not use function with parameter?</p>
  
  <pre><code>// Run correctly
  function loadData(){alert("called");}
  tab=$("#tabID").DataTable({ajax:{url:"a.php",data:loadData}}); //  The "loadData" is called
  ...
  $("#tabID").DataTable().ajax.reload(); //  The "loadData" is called again
  </code></pre>
  
  <hr>
  
  <pre><code>// Problem
  function loadData(A){alert("called with "+A);}
  tab=$("#tabID").DataTable({ajax:{url:"a.php",data:loadData("text")}}); //  The "loadData" is called
  ...
  $("#tabID").DataTable().ajax.reload(); // The "loadData" is NOT called... why?
  </code></pre>
  
  <p>Thank's</p>
