onYouTubeIframeAPIReady与jQuery无法正常工作

Question

我没有调用onYouTubeIframeAPIReady（）函数。我有div为你管视频 <div class="panel-body custom-content-part"></div>

这是使用

的jquery代码

     var html   = '<iframe id="ik_player_iframe" frameborder="0" src="http://www.youtube.com/embed/' +
                        videoId +'??enablejsapi=1&version=3" width="100%" height="420"></iframe>';

        $('#content-view .custom-content-part').html(html);                 

        //Holds a reference to the YouTube player
        var ik_player;          
        //this function is called by the API

        function onYouTubeIframeAPIReady() {
          //creates the player object
          ik_player = new YT.Player('ik_player_iframe'); 
          console.log('Video API is loaded');                  
          //subscribe to events
          ik_player.addEventListener("onReady","onYouTubePlayerReady"); 
          ik_player.addEventListener("onStateChange","onYouTubePlayerStateChange");
        }

        function onYouTubePlayerReady() {
          console.log('Video is ready to play');
        }   

        function onYouTubePlayerStateChange(event) {
          console.log('Video state changed');
        }

某种方式onYouTubeIframeAPIReady的方法永远不会被触发。
