Event for controller changing model in Ember?

Question

Is there an event or a hook that should be used to capture when a controller is initialized after being instantiated, or reinitialized for a specific route?

I've already tried init() - but my controller is only instantiated once for the life of the application, but supports multiple models depending on the route. What I need to capture is when the model of the controller changes, or some moment after instantiation when the route changes.

I've also tried setting a computed property, but it isn't really appropriate, since I need an event to fire a function when the model changes - not only when the property is called.

Any help is very appreciated.

Edit: Aha! I completely looked over the fact that I can set observes() on my function, so that it will fire when the model changes.

So, my answer was to do the following:

dependency: function() {
    console.log('the model has changed');

    //...other stuff...
}.observes('model')
