Not working in lazy loaded module

[d3473r]

Hi,

having a similar issue like #35.
When i want to show a notification and then navigating away (e.g. after sending a form) the notification is immediately cut away.
I think this happens because i have to use a notifier-container> in each lazy loaded module separately.
If i put the notifier-container> only on the root component i cannot show notifications from lazy loaded modules otherwise.

Regards
