Update counter wishlist without reload

Hi I’m using yith wishlist plugin and I’m trying to update the wishlist counter without reloading the page, i have added this code at functions.php

 if ( defined( 'YITH_WCWL' ) && ! function_exists( 'yith_wcwl_get_items_count' ) ) {
  function yith_wcwl_get_items_count() {
    ob_start();
    ?>
       <div class="header-wishlist">
		<a href="<?php echo esc_url( YITH_WCWL()->get_wishlist_url() ); ?>">
			<span class="yith-wcwl-items-count">
				<i class="yith-wcwl-icon fa fa-heart-o"></i>
					<?php 
						$count = YITH_WCWL()->count_products(); 
						if ( $count > 0 ) {
							echo '<span class="wishlist-count">' . esc_html( $count ) . '</span>';
						}
					?>
			</span>
		</a>
	</div>
    <?php
    return ob_get_clean();
  }

  add_shortcode( 'yith_wcwl_items_count', 'yith_wcwl_get_items_count' );
}

if ( defined( 'YITH_WCWL' ) && ! function_exists( 'yith_wcwl_ajax_update_count' ) ) {
    function yith_wcwl_ajax_update_count() {
        // Count all wishlist products
        wp_send_json(
            array(
                'count' => YITH_WCWL()->count_products(),
            )
        );
    }
    add_action( 'wp_ajax_yith_wcwl_update_wishlist_count', 'yith_wcwl_ajax_update_count' );
    add_action( 'wp_ajax_nopriv_yith_wcwl_update_wishlist_count', 'yith_wcwl_ajax_update_count' );
}


if ( defined( 'YITH_WCWL' ) && ! function_exists( 'yith_wcwl_enqueue_custom_script' ) ) {
    function yith_wcwl_enqueue_custom_script() {
        wp_enqueue_script( 'jquery' ); 

        wp_add_inline_script( 'jquery', "
            jQuery( function( $ ) {
                let refreshCounter =  () => {
                    $.get( yith_wcwl_l10n.ajax_url, {
                        action: 'yith_wcwl_update_wishlist_count'
                    }, function( data ) {
                        $('.menu-item-wishlist').find('.mini-item-counter').html( data.count );
                    });
                };
                
                $( document ).on( 'added_to_wishlist removed_from_wishlist', refreshCounter );

                // Listen for the custom event on DOM updates
                $( document ).on( 'yith_wcwl_wishlist_updated', refreshCounter );

                // Initial count refresh
                refreshCounter();
            });
        ");
    }
    add_action( 'wp_enqueue_scripts', 'yith_wcwl_enqueue_custom_script', 20 );
}

This action: yith_wcwl_update_wishlist_count happens just the first time the page is open and when i click to add or remove an item it doesn’t happened, this is the url wp-admin/admin-ajax.php?action=yith_wcwl_update_wishlist_count. And this happens when i add a new item it/wp-json/yith/wishlist/v1/items?_locale=user
