ng4 highlight works on ngAfterViewChecked hook but not on ngAfterViewInit

[Maksim Kostromin]

Hello, for some reasons I wasn't able to highlight a code using ngAfterViewInit hook.
After few tries I was succeed with AfterViewChecked interface.

here is a code sample

if it's expected behavior, then maybe better update documentation.
