Backbone JS 单击事件处理程序不起作用

Question

我试图将点击事件处理程序添加到我的 backbone javascript 文件中。但它显示错误："Uncaught TypeError: Cannot read property 'html' of undefined." 这是代码。任何帮助，将不胜感激。 main.js 文件

    var Song = Backbone.Model.extend();

var SongView = Backbone.Model.extend({
events: {
    "click": "onClick",
    "click .bookmark": "onClickBookmark"
},
onClick: function(){
    console.log("Listen Clicked");
},

onClickBookmark: function(e){
    e.stopPropagation();

    console.log("Bookmark Clicked");
},

render: function(){
this.$el.html(this.model.get("title") + " <button>Listen</button> <button class='bookmark'> Bookmark</button>");

    return this;
}
 });

 var song = new Song({title: "sky is sdv sv"});

 var songView = new SongView({el: "#container", model: song});
 songView.render();
