Backbone.js Persisting child variables to parent
What is the correct way to persist an inherited variable, on action to the parent in Backbone.js?
I can see some logical ways to do this but they seem inefficient and thought it might be worth asking for another opinion.

The two classes are both views which construct a new model to be saved to a collection, the parent passing a variable through to a popup window where this variable can be set.
