Datepicker requiring page refresh to operate after first operation - what do I need to reset ?

Datepicker requiring page refresh to operate after first operation - what do I need to reset ?

I'm using Datepicker on an input field , eg:

<input type='text' name='next_send' class='DateInputField' value='18-APR-2013' maxsize='15' size='15'>

The DIV is (re)loaded by a jQuery load() call, ie:

      $("#results").load(g_cgi + "?action=SDIeditForm&NoticeID=" + l_NoticeID,
                     function () {
                         $('.DateInputField').datepicker({ dateFormat: 'dd-M-yy', minDate: '-1m', maxDate: '+2y' });
                     } );

The first time I go to the page, the Datepicker works fine. When I subsequently load the page again it does not re-instate the focus or change events - and therefore does not work atall !

It was previously attached to a $(document).ready event, but after reading a post here I changed it to the recommended "initiate after $.load()" style, but it made no difference. I also tried preceding it immediately with a $('.DateInputField').datepicker( 'destroy' ); call, but that didn't change anything.

If I refresh the page in the browser and then reload the page, it works again: but again only the first time.

Sorry - it's not on a public site, so I can't refer you to a URL.

Incidentally, I made some css tweaks in my css file to stop it flickering / make the prev/next buttons work, etc:

  /* move the prev/next buttons - they ship one above the other and are unusable as they move when hovered */
  a.ui-datepicker-prev {
    float: left; /* place the prev button on the left of the widget - same line as the month */
  }
  a.ui-datepicker-next {
    float: right; /* place the next button on the right of the widget */
  }
  .ui-datepicker-prev-hover,
  .ui-datepicker-next-hover {
    border: none;  /* stops the hovering over the prev/next buttons from affecting the rest of the dialogue */
  }
  .ui-datepicker-title {
    text-align: center;
    font-size: 0.8em;  /* Otherwise "September" is placed on the line below the prev/next buttons */
  }
