Gravity form gform_after_submission woocommerce not working

I have a problem linking my the Gravity Forms' gform_after_submission form/action with the products in WooCommerce.

I've inserted this code in my functions.php

add_action("gform_after_submission_49", "set_post_content", 10, 2);
function wdm_attribute_filter($entry, $form){

    //getting post
    $post = get_post($entry["post_id"]);
    $scelta = $entry[9];

    $loop = new WP_Query( array( 
        'post_type' => 'product',    
        'tax_query' => array(
        'relation' => 'AND',
        array(
            'taxonomy' => 'concern',
            'field' => 'slug',
            'terms' => $concern
        ),
        ),

        'orderby' => 'title',
        'posts_per_page' => '-1', 
        'order' => 'ASC'
      ) 
   );
}

But it's not working.
