Observing changes on any field in bound model in Controller

I'm binding a model to my Controller and I'd like to observe any changes to its fields so I can reload some data and refresh a view.

Right now I have something really non-DRY like this:

goalController = Ember.Object.create({
  ...
  recompute: function() { save model, load recomputed data from server }
  ...
  nameChanged: function() { this.recompute() }.observes('content.name'),
  incomeChanged: function() { this.recompute() }.observes('content.income')  
});

Is there a Ember-y way of doing this?

You can setup multiple observers at a time, so you could rewrite your example like so:

goalController = Ember.Object.create({

    goalUpdated: function() {
        // do your thing
    }.observes("content.name", "content.income")

});
