What is the reason for not updating the cart when clicking +-?

Question

WooCommerce

Good afternoon, tell me how to auto-update the basket when you press the + and - keys.
The problem is that if you enter a number into the input, then the basket will be updated, but if you click on + or -, then nothing happens?

Here is the script that I use to update the cart

add_action( 'wp_footer', 'cart_refresh_update_qty', 100 );

function cart_refresh_update_qty() {
    if ( is_cart() ) {
        ?>
        <script type="text/javascript">
            jQuery('div.woocommerce').on('change', 'input.qty', function(){
                setTimeout(function() {
                    jQuery('[name="update_cart"]').trigger('click');
                }, 100 );
            });
        </script>
        <?php
    }
}

Judging by your code, the script will only work on the field change event

....
on('change', ...
.....

And if you want the same script to work on pressing + or -, then add the corresponding event.

$(":input").bind('keyup mouseup', function () {
