Пакет галереи ngx onClick не работает

Question

galleryAction: NgxGalleryAction [];

Ниже написан код метода ngOnInit ()

this.galleryOptions = [
     { "image": false, "preview": false, "thumbnailActions": this.galleryAction, "height": "515px", "width": "1200px", "thumbnailsRows": 3, "thumbnailsColumns": 7, "thumbnailsMargin": 10, "thumbnailsPercent": 100, },
     { "breakpoint": 500, },
   ];

   this.handleClick = this.handleClick.bind(this);
   this.galleryAction = [{ icon: "TestData", onClick: this.handleClick }];
