One problem is - does the doSomething() take a long time? Hard to say from looking at it, but if you put that call in a click handler and it does take a long time to resolve, you'll be blocking execution Everywhere Else on the page (single-threaded and all). That's generally a good reason to put things in a $timeout, IMO.
It's worth noting that $timeout is better to use here than setTimeout, as it wraps the timed-out call in a scope.apply to make sure that angular is notified of any changes you make to models inside that call. That said, in general I've not had issues with calling functions passed in to a directive using & parameters. Sander's also right - if you need a digest cycle to run in there, you need to release control of the thread and let angular do its thing. Cooperative multitasking, basically.
