Clojurescript One: distinguishing event sources / multiple widget instances

Pretty basic question here. Suppose I want to have 2 copies of the form in the same application. How will the event handlers know which form the events are coming from, and which form needs to be modified in response to those events? More generally, what if I have N copies of some widget that al
