I can't validate if the toggle is checked

[RamsesSerna]

I'm having this trouble.

I'm traying to verify if the checkbox is checked when the element changes but the element never change it state. Here is the code:

$('#ws_swtch').change(function (e) {
  e.preventDefault();

  if ($(this).is(':checked')) {
    $('#col_url').removeClass('oculto');
    $('#col_catalogo').addClass('oculto');
   } else {
    $('#col_catalogo').removeClass('oculto');
    $('#col_url').addClass('oculto');
   }
});
