title: jQuery Datepicker "After Update" Event or equivalent
body: <p>I am using a standard jQuery Datepicker and I need to modify the text in each TD based on some daily status information. I realize I can wire up the <code>beforeShowDay</code> event but that only allows me to modify CSS information for each date. Hoping for an event on the entire calendar such as <code>afterRender</code> etc.</p>
  <p>I can modify the first calendar that is displayed but if the user changes months or years, I (or my code) is out of the loop.</p>
