asp.net按钮不在jquery对话框中触发

Question

我试图点击jQuery对话框中的ASP.net按钮，但它没有触发。

<div id="dialog" style="display: none">
  <label >Item Name</label>
  <br />
  <asp:TextBox ID="txtItemNames" runat="server" CssClass="form-control-new"></asp:TextBox>
  <br />
  <asp:TextBox ID="txtItemNames2" runat="server" CssClass="form-control-new"></asp:TextBox>
  <asp:Button ID="btnSaveChild" runat="server" Text="Save" OnClick="btnAdd_Click" />
</div>

<script type="text/javascript">
  $("[id*=btnItemType]").live("click", function () {
      $("#dialog").dialog({
          title: "Item Asset Details",
          width: 500,
          height: 500,
          buttons: {
              Close: function () {
                  $(this).dialog('close');
              }
          },
          modal: true
      });
      return false;
  });        
</script>
