title: How to add onChange event to dropdown boxes of JQuery.DatePicker
body: <p>I have the following situation: <a href="http://jsfiddle.net/ff6Ex/" rel="nofollow">Fiddle</a></p>
  
  <p>What I want, is to add an <code>onChange</code> event to the dropdown boxes of the <code>datepicker</code> so that I will be able to capture the selected month/year in the text box above as a new value is selected from the calendar. </p>
  
  <p>PS: Inspecting the relevant dropdown boxes, there is already an <code>onChange</code> command assigned that looks like </p>
  
  <pre><code>onchange="DP_jQuery_1353406309923.datepicker._selectMonthYear('#datepicker', this, 'M');"
  </code></pre>
  
  <p>I don't want to overwrite this. </p>
  
  <p>Thanks in advance</p>
