Change event does not propagate from Backbone Collection to Backbone Model

I have a Backbone Model that has Backbone Collections for some of its attributes.

When a change event is triggered on one of these collections, it does not propagate to the parent model.

Is it possible to change this, so that the event does propagate?

It's the other way round, model change events trigger collection change event. If you don't like the way answer by metadept is the solution - Deeptechtons

Provided you're not referencing a collection that the model's part of (which would create circular logic), you should be able to bind it explicitly:

model.listenTo(model.collection, 'change', function() {
        model.trigger('change');
    });

Here's a jsFiddle that seems to be working: http://jsfiddle.net/2Nctk/2/
