I'm using a virtual keyboard. I have a checkbox that controls whether the virtual keyboard is displayed or not. The thing is that I don't understand how to disable it. I try to unbind it but it doesn't work...

I also tried to use namespaces and then unbind all namespaces but still the keyboard remains accessible after a click on the text box.

<input class="virtualKeyboardField ui-keyboard-input ui-widget-content ui-corner-all" data-val="true" data-val-required="The User name field is required." id="loginUserName" name="UserName" type="text" value="" aria-haspopup="true" role="textbox">
<script type="text/javascript">
  $(function () {
    //show login
    $("#showLogin").on({
      click: function () {
        $("#loginFormDiv").toggle("slow");
      }
    });
    $("#cb_showVKey").on('click', CheckIsToShowKey);
  });
  function CheckIsToShowKey(event) {
    //var isCheck = $("#cb_showVKey").is(':checked');
    //alert("ischecked? " + isCheck);
    if ($("#cb_showVKey").is(':checked')) {
      //if checked
      BindKeyboards();
    } else {
      //not checked
      UnBindKeyboards();
    }
  }
  function bindVirtualKeyboards() {
    $("#loginForm").delegate(".virtualKeyboardField", "click.xpto", BindKeyboards);
  }
  function UnBindKeyboards() {
    $("#loginForm").undelegate(".virtualKeyboardField", "click.xpto", BindKeyboards);
  }
  function BindKeyboards() {
    // alert(event.currentTarget.id);
    //alert("xpto");
    if ($("#cb_showVKey").is(':checked')) {
      $("#loginUserName").keyboard({
        layout: 'qwerty',
        lockInput: true,
        preventPaste: true
      });
      $("#loginUserPassword").keyboard({
        layout: 'qwerty',
        lockInput: true,
        preventPaste: true
      });
    }
  }
  $(document).ready(function () {
    $("#loginForm").validate();
    BindKeyboards();
  });
</script>

Any help guys?
