Jquery, window.send_to_editor and widget issue

I’m implementing some widget that can select some images from the media library ( via thickbox ) and send the result to an input box. But if set the right id of the input box into jQuery statement, after i select “insert into post”, nothing appear into the input. It appear only if i select the id of the current sidebar, which means if i move the widget into another sidebar it won’t works.

There is a solution?
