Hi, I try to update a subfield of repeater for count click on an ad image.

I’ve tried this solution but don’t work properly. Can you help me?

HTML
<a href="https://google.it" class="count" data-post="1" data-row="$i"><img src="/image.jpg"></a>

JS

jQuery( ".count" ).click(function($) {
    var post_id = $(this).data('post'); 
    var row     = $(this).data('row'); 
    $.ajax({
     type:"POST",
     url: 'https://site.com/wp-admin/admin-ajax.php',
     data: {
        'action':'update_counter',
        'post_id' : $post_id,
        'row' : $row
     }
     }); 
});

PHP (in plugin function.php)

function update_counter() {
    $post_id = trim($_POST['post_id']);
    $row     = trim($_POST['row']);
    update_sub_field( array('ad', $row, 'click'), 'Test', $post_id);
    exit();
}
add_action('wp_ajax_update_counter', 'update_counter');
add_action('wp_ajax_nopriv_update_counter', 'update_counter');

Best Regards
