Add Page Moved Trigger to moveToPage

[ViViDboarder]

Adding a new trigger to the end of the moveToPage function so that
async events can be added by the user to be triggered whenever new data
is shown on the table.

Hmm, actually the pagerChange event is fired when the renderAjax function has completed processing data.

So actually, pageMoved is most likely fired before the ajax call completes.

Right, I actually use it to trigger an ajax call. So after the page moves it calls back to pageMoved which pings my server and updates some of the table.
