title: JQuery UI Autocomplete callback
body: <p>Is it possible to define a callback function to an input which <a href="http://jqueryui.com/demos/autocomplete/">JQuery Autocomplete</a> plugin has been applied to.</p>
  
  <p>I actually want to execute something on the onchange event, but, weirdly, it is triggered before the value is set. The input has a blank value when the onchage event is triggered.</p>
