Dependent exposed filter using jQuery

Hi,

I created two expanded filters (BEF) with radio buttons and auto-submit.

I'm making dependent filters using the following code

    $("#edit-tid-4").live("click change", function(){
    $('#edit-tid-1-8').attr('disabled','disabled');
    });

The code works, the required radio button becomes inactive, but only without auto-submit.

Can someone help with the code? If you're strong in jQuery, how can I extend the life of the event or call it again after the AJAX processing is complete?

Thank you...
