          if(event){
            if (event.type === TouchType.Down) {
              this.eventType = 'Down'
            }
            if (event.type === TouchType.Up) {
              this.eventType = 'Up'
            }
            if (event.type === TouchType.Move) {
              this.eventType = 'Move'
            }
