Lazy reference selector - on change event

I am not able to access the partner portal - keeps giving me the options to register or login. The lazy reference selector which I found in the app store today is great and solves my problem described in this thread: Reference selector is blank However it does not seem to be supporting on change events (yet). Is it feasible to add this functionality?
