Angular 5 - generic component child used in several main component not working

[XavierDeLapeyre]

Hi all
I am new to Angular ( working on Angular 5 )

I found this great module and it fits my needs.
I manage to make it work fine if I place the code in my main component
Ex :
App - component home
App - component login
App - component password

but it is kind of tedious and from what the team is planning there will be lots of main components.

So I thought of adding a child component ( like footer/header etc ) and created an idle child component that I placed on all my templates.

My issue is that it triggers on the first page load, but once I start navigating to other routes, the component does not trigger itself or does not reset itself. Tough for me to say for sure.

Is there a way to create an idle component that I could reuse in all my other main components?
