No since I changed again to that onSuccess solution which seemed to work again now. I was just going to re-test it in other browsers. If that works, I'll keep it as is.

Also, I've changed the binding to be for #flexClients not for #flexClients tr, may be that's what made the original difference

UPDATE. In Google Chrome it doesn't seem to work :(

UPDATE2. I reloaded and it doesn't work in FireFox either. So, perhaps it worked due to several break points. Without these break points it doesn't work.
