Bug causes listeners to be registered many times

[ckosmowski]

Steps to reproduce:

• Create a DobyGrid, Use a Backbone collection as the data source
• Set some options via setOptions()
• Now all bound Data events (add, remove etc...) will fire twice

This is because of two different callstacks:

1.) initialize() -> validateOptions() -> bindToCollection() 2.) setOptions() -> validateOptions() -> bindToCollection()

Took me hours to find out why the add method is called twice with the exact same callstack. Can you fix this or give us a hint on how you want this to be fixed?

Thanks for tracking that down. That's a serious issue. Not sure what the right solution is yet, will have to do a code review.

My quickfix was to add self.stopListening(self.options.data); as the first line of bindToCollection()
