title: Jquery UI Datepicker
body: <p>I'd like to change the Default <code>altFormat</code>, but I can't seem to get it to work. </p>
  
  <pre><code>$("#myFav").datepicker({ dateFormat: 'yy-mm-dd' });
  $("#myFav").datepicker('option', 'dateFormat', 'yy-mm-dd');
  </code></pre>
  
  <p>I thought altFormat would work just the same? </p>
