Getting formItem when capture key event

Well we want to know from where is triggered an event key.
Closer method to get element we have found is
isc.Event.getActiveElement()
But it doesn't returns exactly the same object than form.getField("fieldWhenTrigger").
How to get the itemForm element from which has triggered event?
Thanks.
