I'm not familiar with the Backbone code or config. However, it sounds like you are setting an argument by specifying a function name in a string. If you want to specify multiple functions, then instead of specifying them in a string I'd say Backbone should accept either a string or a function as the argument value. That would let you define your event handler in-place, and you could define one that just calls a series of other functions.
