custombox模态中的ASP.NET按钮未触发单击事件

嗨，我在我的asp.net网站上使用custombox modal，modal工作得很好，但modal页脚内的按钮BTNConfirm_Click即使是也不会触发点击

我对打开模态没有问题我对模态页脚内的按钮（BTNConfirm_Click）没有问题，即使（OnClick）也没有点击

我的调用模式函数：

    <script>
    $(function Modal() {
        $('#LkForget').on('click', function (e) {
            Custombox.open({
                target: 'Page/ForgotPassword.aspx',
                effect: 'fadein'
            });
            e.preventDefault();
        });
    });
</script>

我的LinkButton调用函数Modal:

<asp:LinkButton Style="font-size: 13px; color: #FFF; font-family: yekan,tahoma; margin-right: 92px;"
                                ID="LkForget" runat="server" OnClientClick="Modal()">Forgot Password</asp:LinkButton>

我的代码：

<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<div>
    <div class="Modal">
        <button type="button" class="close" onclick="Custombox.close();">
            <span>×</span><span class="sr-only">Close</span>
        </button>
        <h4>
            Forgot password</h4>
        <table class="fullWidth" style="margin: 15px; line-height: 35px; text-align: left;">
            <tr>
