I'm trying to manupilate the input checkbox however everytime i click on the label the first time the checkbox will be selected after that i click the label again and the checkbox is unchecked so far so good. But when i click the label again the checkbox will not be checked.
My jQuery code is as followed
$('.form-checkbox label').on('click', function(e) {
    e.preventDefault();
        if ($(this).hasClass('checked')) {
            $(this).removeClass('checked');
            $(this).find('span').removeClass('checked');
            $(this).find('input').attr('CHECKED', false);
        } else {
            $(this).addClass('checked');
            $(this).find('span').addClass('checked');
            $(this).find('input').attr('CHECKED', true);
        }
    });
And my HTML is as followed
<div class="form-checkbox">
   <label id="checkbox-checkbox">
      <input id="checkbox-checkbox" name="checkbox" value="option1" type="checkbox" /><span></span> Option 1
   </label>
</div>
