        <div class="personalInfo">
          <table class="tableOverride table-responsive">
            <tr>
              <th>Mobile Number:
              </th>
              <td>
                <asp:TextBox ID="txtBoxMobileNum" runat="server" CssClass="form-controlOverride"></asp:TextBox>
              </td>
            </tr>
            <tr>
              <th>Home Number:
              </th>
              <td>
                <asp:TextBox ID="txtBoxHomeNum" runat="server" CssClass="form-controlOverride"></asp:TextBox>
              </td>
            </tr>
            <tr>
              <th>Personal Email:
              </th>
              <td>
                <asp:TextBox ID="txtBoxPersonalEmail" runat="server" CssClass="form-controlOverride"></asp:TextBox>
              </td>
            </tr>
          </table>
        </div>

        <div>
          <div class="text-center">
            <button id="clonePersonalInfo" class="btn btn-default" style="height: 30px; text-decoration: underline;">Add Contact Information</button>
          </div>
          <div class="pull-left">
            <asp:Button ID="btnSavePersonalInfo" runat="server" Text="Save" Width="100px" Height="30px" CssClass="btn btn-primary" />
          </div>
        </div>
    </ContentTemplate>
</asp:UpdatePanel>
</pre>

What I have tried:

jquery Code:

JavaScript

$(document).ready(function () {
    $('#clonePersonalInfo').click(function () {
        $('div.personalInfo').after(function () {
            return $(this).clone();
        });
    });
});

jQuery cannot appear or disappear, especially in seconds. This is just a library. :-)
Something is disappearing only if you program it this way. I'm not sure you show all relevant code.

You need to debug it and provide more info. Not sure how we can help. What does "disappearing" mean here?

< button > always submits (thus going to the server and refreshing the page). This will (ofcourse) remove your added element.

To solve this, return false from the click handler like this:
