backbone.js - BackboneJS单击事件未触发

Question

我知道以前有人问过这个问题，但我找不到正确的答案，尽管它很简单:

我的 HTML 模板中有这个:

<div id="vid"></div>
<button class="mdk-close">x</button>

这在我看来:

function (App, Backbone, ArtistVideos, Artistimg, Artistname) {

    var ArtistVideoPopup = App.module();

    ArtistVideoPopup.View = Backbone.View.extend({
        template: 'artistYoutubeVideo',
        events: {
            "click .mdk-close": "test"
        },
        test: function() {
            alert('dasdasas')
        },  
        beforeRender: function() {
            var artistimgCollection = new Artistimg.ArtistimgCollection();
            artistimgCollection.artist_id = this.artist_id;
            this.insertView('.artistImage', new Artistimg.View({collection: artistimgCollection}));
            artistimgCollection.fetch();

            var artistnameCollection = new Artistname.ArtistnameCollection();
            artistnameCollection.artist_id = this.artist_id;
            this.insertView('.artistName', new Artistname.View({collection: artistnameCollection}));
            artistnameCollection.fetch();

            var artistvideosModel = new ArtistVideos.ArtistVideosModel();
            artistvideosModel.artist_id = this.artist_id;
            artistvideosModel.video_youtube_id = this.video_youtube_id;
            artistvideosModel.fetch();
        },      

        afterRender: function() {

            $('ul.acmenu li a.selected').removeClass('selected');
            $('ul.acmenu li a.artistVideos').addClass('selected');

            var tag = document.createElement('script');
            tag.src = "https://www.youtube.com/iframe_api";
            var firstScriptTag = document.getElementsByTagName('script')[0];
            firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

            var player;
            window.onYouTubeIframeAPIReady = _.bind(function() {
              player = new YT.Player('vid', {
                height: '480',
                width: '853',
                videoId: this.video_youtube_id,
                events: {
                  onReady: onPlayerReady,
                  onStateChange: onPlayerStateChange
                }
             })
            }, this);

            function onPlayerReady(event) {
                event.target.playVideo();
            }

            var done = false;
            function onPlayerStateChange(event) {
                // if (event.data == YT.PlayerState.PLAYING && !done) {
                    // setTimeout(stopVideo, 6000);
                    // done = true;
                // }
            }
            function stopVideo() {
                player.stopVideo();
            }


        },



    });

    return ArtistVideoPopup;
}

但事件根本没有触发。有谁知道可能是什么问题？

提前致谢...

events在您看来，只绑定(bind)到 view.el 内的元素
