title: Jquery UI datepicker plugin - How to change alt field?
body: <p>I have an issue where a user changes a date directly in the input field the alt field does not update. The only time the alt field updates is when the calendar is used to select a specific day.</p>
  
  <p>Code example:</p>
  
  <pre><code>$this
  .find('#'+strInputID)
  .datepicker({altField: '#alt_'+strInputID, altFormat: 'dd/mm/yy', minDate: new Date()})
  .datepicker("setDate" , dDfltDate);
  </code></pre>
  
  <p>Please note that I am using altFormat because the input field changes depending on localisation, so I can't copy the value across directly whenever the input has changed.</p>
  
  <p>Does Jquery Datepicker have anything to allow for this?</p>
  
  <p>The events list here does not have what I want: <a href="http://jqueryui.com/demos/datepicker/" rel="nofollow">http://jqueryui.com/demos/datepicker/</a></p>
  
  <p>Does anyone have any answers to how this could be fixed?</p>
  
  <p><strong>EDIT:</strong> 
  This example <a href="http://jqueryui.com/demos/datepicker/#alt-field" rel="nofollow">http://jqueryui.com/demos/datepicker/#alt-field</a>
  works, I found another example that didn't. As we are using v1.7.3 and not 1.8.8 I can assume that this might be the problem. </p>
  
  <p>I can not upgrade so I will continue to test and see if this is definately the case. If anyone knows otherwise then please let me know. Thanks</p>
