Why is the checkbox not working when clicking on label via id in IE8?

Question

HTML

Why might the checkbox not work when clicking on label via id in IE8? The checkmark does not appear when clicked.
View markup

.container
                        input#check(type="checkbox")
                        label(for="check")
                            | Текст

At the same time, the js code for checking the activation of the checkbox is triggered

$('.js-check').on('click', function () {
      $(this).parents('.js-check-parent').find('.js-send').prop('disabled', function(i, v) { return !v; });
 });
