Refresh variation product description after variant changed in Woocommerce

Question

so I've moved variation description to additional information tab in single product page, everything work like a charm, but description of each variant shows only when I click on anything at page. Of course I'd like to have it refresh instantly after variant is chosen. I've got Variation Swatches for WooCommerce plugin, which cause whole problem.

That's a piece of code I used (created by LoicTheAztec)

add_action( 'wp_footer', 'move_variation_description' );
function move_variation_description(){
    global $product;
    // Only on single product pages for variable products
    if ( ! ( is_product() && $product->is_type('variable') ) ) return;
    // jQuery code
    ?>
    <script type="text/javascript">
        jQuery(function($){
            a = '.woocommerce-variation-description', b = a+' p', c = 'input.variation_id',
            d = '#tab-additional_information', de = $(d).html();

            // On load, adding a mandatory very small delay
            setTimeout(function(){
                // variation ID selected by default
                if( '' != $(c).val() && $(a).text() != '' )
                    $(d).html($(a).html());
            }, 300);

            // On live event (attribute select fields change)
            $('table.variations ul li').on( 'blur', function(){
                // variation ID is selected
                
               
                if( '' != $(c).val() && $(a).text() != '' ){
                    $(d).html($(a).html()); 

                }
                // No variation ID selected
                else {
                    $(d).html($(a).html()); // We set back the variable product description
                }
        
            });
        });

 

    </script>

I've tried to make some script to trigger a click (as I said, when I click whatever on page, description refresh) but it doesn't work either, can anybody help?
