angular2 call function of parent component

I would create a custom event in the child component. Something like this:

@Component({
  selector: 'child-comp',
  (...)
})
export class ChildComponent {
  @Output()
  uploaded = new EventEmitter<string>();

  uploadComplete() {
    this.uploaded.emit('complete');
  }

Your parent component could register on this event

@Component({
  template `
    <child-comp (uploaded)="someMethod($event)"></child-comp>
  `,
  directives: [ ChildComponent ]
})
export class ParentComponent {
  (...)

  someMethod(event) {
  }
}

Another way would be to inject the parent component in the child one, but they will be strongly linked together...

Below is the code that worked for me in the latest

Angular 5+

class ChildComponent {
  @Output() myEvent = new EventEmitter<string>();

  callParent() {
    this.myEvent.emit('eventDesc');
  }
}

In ParentTemplate's template

<child-component (myEvent)="anyParentMethod($event)"
