Change events occur too late due to setTimeout

I was having problems with the auto-complete and ajax requests on my application.

I have a search button that uses a Ajax request to update the page.

To replicate the problem I write the complete/correct text on the auto-complete input and instead of clicking the menu I click the button.

Both the focus and the change events are triggered after the Click event of the button occurs ..and that is kinda too late.

I tracked this problem to the following code:

self.closing = setTimeout(function() {

self.close( event );

self._change( event );

}, 150 );

Is it really necessary to have the _change delayed?

It works perfectly if I just leave the close there and do the change right away.
