                </div>

ts file code

@ViewChild('doubleEle') doubleEle:ElementRef;
  private pressGesture:Gesture;
public ngAfterViewInit():void{
    console.log(this.doubleEle);
    this.pressGesture = new Gesture(this.doubleEle.nativeElement);
    this.pressGesture.listen();
    this.pressGesture.on('doubletap',(e:Event)=>{
      console.log(e);
