[jQuery] jqModal rebind after reload

Hi,
I'm using a standard jqModal thing. It works ok until after I reload
the tab with an AJAX call.
Then the .jqModal elements are not bound.
The question is how to re-bind them again?
I've tried
$("#box").jqmAddTrigger(".jqModal");
but it didn't help.
And when I try to re-init the box with:
$("#box").jqm();
after the ajax call, I get an error:
H[this._jqm] is undefined
Any ideas?
thanks!
