引导程序确认不显示按钮

Question

大家好，我对引导程序确认有疑问：不显示按钮。这是代码

$('[data-toggle="confirmation"]').confirmation({
rootSelector: '[data-toggle="confirmation"]',
btnOkLabel: "Elimina",
btnOkIcon: "glyphicon glyphicon-share-alt",
btnOkClass: "btn-success",
btnCancelLabel: "No!",
btnCancelIcon: "glyphicon glyphicon-ban-circle",
btnCancelClass: "btn-danger",
title: "Elimina"
});

这是应该触发确认的linkBut​​ton

<asp:LinkButton runat="server"
data-toggle="confirmation"
data-content="Vuoi rimuovere questo dipendente?"
OnClick="EliminaPersonale_Click" CommandArgument='<%# Eval("CodFis") %>' ToolTip="Elimina dipendente"><span class="glyphicon glyphicon-remove"></span></asp:LinkButton>
