jQuery选项卡不起作用

我的点击功能有一个问题。我已经从jsfiddle.net创建了这个演示。

在此演示中，您可以看到有微笑按钮。当您单击这些按钮时，将在该时间打开一个选项卡。如果单击选项卡区域中的红色按钮，则该选项卡不起作用，可能是发生了问题。

任何人都可以在这里帮助我，问题是什么，解决方案是什么？

标签是正常的，就像这个工作演示

var response = '<div class="icon_b">
            <div class="clickficon"></div>
                <div class="emicon-menu MaterialTabs">

                        <li class="tab active"><a href="#starks-panel1"> TAB1</a></li>
                        <li class="tab"> <a href="#lannisters-panel1"> TAB2</a></li>
                        <li class="tab"> <a href="#targaryens-panel1"> TAB3</a><span></span></li>
