title: Alternative to onChange or onBlur in jQuery dropdownchecklist control
body: <p>Currently using the jquery dropdownchecklist found here:
  <a href="http://dropdown-check-list.googlecode.com/svn/trunk/src/demo.html" rel="nofollow noreferrer">http://dropdown-check-list.googlecode.com/svn/trunk/src/demo.html</a></p>
  
  <p>I'm doing some pretty heavy processing of a large quantity of data on the client with a number of dropdownlists. Essentially, and put very simply, as each dropdown changes the data in each is filtered. I'm using the onChange event to do this but with each selection I make (I am able to make multiple selections) the event is fired, which is expected but I'm finding it's really slowing up my app. I'd much rather have the event fire when the dropdownchecklist collapses back up. I've tried using the onBlur event but this isn't happening when the div that contains the options collapses back up, only when the whole control loses focus.</p>
  
  <p>Does anyone know of an event that I can use or that this control has that I can hook into to have my function fire when it collapses rather than when it changes or loses focus?</p>
  
  <p>If not, how easy is it to add the functionality too it?</p>
