woocommerce_product_quick_edit_save hook not fired

I´m trying to add custom fields in the quick edit of woocommerce product. I managed to show fields and populate with jquery but I don´t manage to save data updated.

add_action( 'quick_edit_custom_box', array( $action_class, $quick_edit_method_called ), 99, 3 );
add_action( 'admin_enqueue_scripts', array( $action_class, $quick_edit_script ), 99 );
if( $post_type_slug === 'product' ){
    add_action( 'woocommerce_product_quick_edit_save', array( $action_class, $quick_edit_save_post ), 99, 1 );
}else{
    add_action( 'save_post', array( $action_class, $quick_edit_save_post ), 99, 2 );
}

quick_edit_custom_box and admin_enqueue_scripts work very well but neither woocommerce_product_quick_edit_save nor save_post are fired when the administrator click on button 'update' in quick edit.

To test it, I added wp_die('my test must stop here'); inside $action_class::$quick_edit_save_post(). No success.

Someone has got an idea ?
