Modal PopUp Extender labels wont update on Asynchronous Postback

Question

Hi everyone!

I have a ModalPopUpExtender with an UpdatePanel on it. On the UpdatePanel,there few labels and componentart Grid which Updates from the server on every Asynchronous postback when an image button is clicked. The Problem is that the server code updates the modalpopupextender labels as the information on the grid but it wont display the Updated version of it on the modal Popup Extender. Need some Help... Heres the sample code:
