title: Backbone: adding model from one collection to another
body: <p>Here is the general structure I have right now:</p>
  
  <p>Collection 'A' which has view 'A'</p>
  
  <p>to add a model, you can open a modal and choose from a list. The modal is it's own view, 'B', tied to its own collection, 'B'. the view 'B' is instantiated from view 'A' on a click event.</p>
  
  <p>I was going to initialize view 'B' with a 'myParent' attribute so when a model is selected from collection b, I can say this from within view B:</p>
  
  <p>this.myParent.collection.add(newModel).</p>
  
  <p>I know this will work, but is this coupling things too tight that don't need to be? is there a good pattern for this? I was thinking about having several different events and triggers spread about different places but that seems to just complicate things without much added value.</p>
