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.

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 ?
