Called on a jQuery collection that was rendered with can.View with pending hookups. can.View can render a
template with hookups, but not actually perform the hookup, because it returns a string without actual DOM
elements to hook up to. So hookup performs the hookup and clears the pending hookups, preventing errors in
future templates.
