Related List Headers

I use this to change the headers of my list.

$.each( $("[id*=IHREASON]") , function () {

$(this).closest('th').html('<center><b>If no admitting/discharge <br />diagnosis and inpatient admission <br />was not for a procedure, what <br />was the reason for the <br />inpatient admission?</b></center>');

});

It works great but after I do an inline edit it  goes back to the standard internal name.

I tried this but it does not change the header back. Do you have any suggestions?

$('[id*=IHREASON]').mouseover(function() {

$.each( $("[id*=IHREASON]") , function () {

$(this).closest('th').html('<center><b>If no admitting/discharge <br />diagnosis and inpatient admission <br />was not for a procedure, what <br />was the reason for the <br />inpatient admission?</b></center>');

});

});

Thank you.
