Ember component: bind-attr inside each

I have inherited an ember.js project from another team. So, I'm a total newbie.

I'm trying to render a list of objets and activate the object line when it's clicked.

I've created a component for the object listing but it's not working.

The jsbin bellow shows the approach I'm taking.

Any help would be appreciated.
