azure媒体播放器点击事件

Question

我必须在开启视频时跟踪事件（点击大按钮）。  我显示了关于＆＃34; tech-click＆＃34;的结果。但它没有点击大按钮。

  player = amp(randomId, <any>{
                techOrder: ["azureHtml5JS", "flashSS", "html5FairPlayHLS", "silverlightSS", "html5"],
                "nativeControlsForTouch": false,
                "logo": { "enabled": false },
                controls: true,
                width: attrs.width,
                height: attrs.height,
                autoplay: scope.autoplay,
                poster
            });


  player.addEventListener("tech-click", () => {
        appInsights.trackEvent("homeVideo");                  
  });

document.getElementsByClassName("vjs-big-play-button[0]
.addEventListener("click", () => {
                            appInsights.trackEvent("homeVideo");
                        });
