Ember.js: Computed property of model not rendering in component's reference on change

The issue I am experiencing is quite clearly expressed in this jsbin, where the computed property isFinito does not change in the template along with the value of isFinished. Is this a feature of components, that they can't listen to computed properties of models passed to them ? If so, how can I achieve this. It seems like a very common need but no matter how much I searched about this, I couldn't find something that duplicates this problem or solves it.
