Event or Action bubbling in ember js

Js bin snippet here, where bubbling is not working. http://ift.tt/1yA8Cw8

The ember documentation says,

http://ift.tt/1HRP0wU

Events bubble up from the target view to each parent view in succession, until the root view.

Event also bubbles through the controller and then route hierarchy.

I don't even see events being bubbled to route.
