Compare button added on category pages (archive pages)

In the mean time I found a solution to add the Compare hyperlink under each product listed on the Product Category page (archive page):

In my child-theme, in the functions.php file I added this:
function vald_add_compare_button() {
if ( function_exists(‘woo_add_compare_button’ ) ) echo woo_add_compare_button();
}
add_action( ‘woocommerce_after_shop_loop_item_title’, ‘vald_add_compare_button’ );

The problem is that both the Compare link and the Compare button are displayed, so I added this style in my child-theme CSS:
.woo_grid_compare_button_container {
display:none;
}

I hope this is a correct solution. Probably not the best, but it works for me.
