Angular Youtube - onReady

I am trying to wrap Angular/Youtube component, described here.

This stackblitz is the result.

The problem here is that

<youtube-player  #musicPlayer  [videoId]="extractVideoId(videoId)"  (ready)="onReadyInternal($event)"></youtube-player>

is not firing at all the onReadyevent. I never have my console log.

  onReadyInternal(event: any): void {    console.log(event, 'Is Ready');    this.onReady.emit(event);  }

I based my work on another question with a linked project.The onReady fires normally on this one, and the code looks very similar.
