Onchange on lookup not detect on Rollup 13

Hello everyone,

I ask for your help because I have a problem: since the passage of CRM Rollup 13, the onchange (and perhaps the attachEvent) on my lookup does not work is that someone a solution?

code:

crmForm.all.geo_typeofbusinessid.attachEvent ("onchange", function () {

setSectorAndAsvRelationShip ();

});
