Could you please point me to an example how ghost-ui would add js behaviour. Could not find it in the ghost-ui repo. With Ember you normally need to use the `didInsertElement` hook on a view or put it into the `afterRender` queue of the Runloop. If you don't do this your templates most likely are not rendered at the time you are invoking the additional js.
