Elementor rendering outside regular loop

I update part of a page lately with ajax with posts that have a specific post type and are designed using elementor. On the server, I use this loop to recover the content to be sent, but elementor is not triggered so the content is not rendered correctly. What should I call to fire elementor on this content.

$wpbp = new WP_Query(['post_type' => $type, 'nopaging'=>true, 'post__in'=>$post_id]);
$content = "";
if ($wpbp->have_posts())
	while($wpbp->have_posts())
	{
		$wpbp->the_post();
                $content .= get_the_content();
	}
wp_reset_query();
return do_shortcode($content);
