Jqmodal popups doesnt work with Updatepanel

Question

I have a page with two text boxes,a button(server-side button) and a repeater in an update panel.In repeater there is a link which opens a popup on click.

First time it works ok but after button click the link in repeater doesn't open popup,it redirects the page to link url.

If I remove update panels all works fine but I cannot remove update panels.

Please suggest how to resolve this issue?

Thanks.
