weui 中js 初始化空间，对控件上的自定义组件操作不起作用如何处理

var $dialogue = weui.dialog({
                content: <div id="privacySelect">
                    <div class="weui-cell">
                                <div class="weui-cell__hd">
                                                <input type="radio" name="ttl" id="s11" />
                                <i class="weui-icon-checked"></i>
                    </div>
                                    <div class="weui-cell__bd">
                                                        <label>abc</label>
                                </div>
                    </div>
                    <div class ="weui-cell">' +
                                <div class="weui-cell__hd">' +
                                                <input type="radio" name="1344"  id="s12"/>
                                </div>
                                        <div class="weui-cell__bd">' +
                                                    <label>1234</label>' +
                                    </div>
                    </div>
                    <div class="weui-cell">
                                <div class="weui-cell__hd">' +
                                        <input type="radio" name="1234"  id="s13"/>' +
                                        <i class="weui-icon-checked"></i>'
                                </div>
                                <div class="weui-cell__bd">
                                        <label>5445433</label>
                            </div>
                    </div>
                    <div class="weui-cell">
                            <div class="weui-cell__hd">
                                            <input type="radio" name="1234"  id="s14" checked />
                                            <i class="weui-icon-checked"></i>
                            </div>
                            <div class="weui-cell__bd">
                                            <label>全部</label>

                    onClick: function() {
                        $dialogue.hide();
                    }
                }]
            });
            $("#s14").on("click",function(){


            });

$("#s14").on("click",function(){


}); 事件代码不起作用

    $('body').on('click', '#s14, function () {     
        alert('我是有效的on方法,你能看见我吗：' );  
    });
