Thanks! That totally makes sense, please disregard my comment about a separate view. Alright, let's extract this "on" listener to ./app/helpers, might be Application.js with function preinitialisation, so then we can call it like this: App.preinitialisation(). Sounds good?

PS. I'm not going tilting at windmills right now, however sooner or later we'll need to figure out that extra cost for additional emberjs view.
