title: How to set the action of a NSButton in a binding scenario?
body: <p>I have a button that is inside a view repeated inside a NSCollectionView. I can bind the title of the button to one of the properties in my model class but I want to wire the selector of the button to one of the selectors in my model class. Obviously, the button must send the message to the model object associated with the corresponding collection view item.
  I managed to bind the target for the button but how to set the selector? I want to do that in Interface Builder if possible...</p>
