Answer 1

With child in router-outlet, you can use ContentChild to be able to call a method in the child. So...

import { ContentChild } from '@angular/core';

in your parent:

@ContentChild(ChildComponent)
private childComponent: ChildComponent;

and on your click event do:

this.childComponent.doSomething()

Also you need to add your child component in the providers array in parent:

@Component({
  selector: 'parent',
  ...
  providers: [ChildComponent]
})
