bbPress.org

I am trying to replace all the topics in a specific forum with the new topic form whenever I press on the Create New Topic button.
Then I tried to ajaxify it using the shortcode [bbp-topic-form], but the form didn’t showed up…

In the functions.php I have added this:

wp_enqueue_script( 'script', get_stylesheet_directory_uri() . '/js/topicButton.js', array ( 'jquery' ), 1.1, true);
wp_localize_script( 'script', 'script', array(
	'ajaxurl' => admin_url( 'admin-ajax.php' )
));
..
..
add_action('wp_ajax_script', 'scriptfunc');
add_action('wp_ajax_nopriv_script', 'scriptfunc');
function scriptfunc() {
	echo do_shortcode("[bbp-topic-form]");
	die();
} 

The ajax file

(function($) {
	
		function find_forum_id() {
			var forumidval = document.getElementsByTagName("article")[0].id;
			forumidval = forumidval.replace(/\D/g,'');
			return parseInt( forumidval );
		}
	
		$(document).on( 'click', '.bbp-new-topic-button', function( event ) {
			event.preventDefault();
			
			forumid = find_forum_id();
			
			$.ajax({
				url: ajaxurl,
				type: 'post',
				data: {
					action: 'scriptfunc',
					forumid: forumid
				},
				beforeSend: function() {
					$('.bbp-topics').remove();
				},
				success: function( html ) {
					$('article').append( html );
				}
			})
		
		});
 })(jQuery);
