Hi, I have form like extend
I add to function

if(Director::is_ajax()){
			return $this -> renderWith("Footer");
		} else {//DO SOMETHING}

How to call in js to this function from Form ("AddObiekt")

When in JS add url: ajax/AddObiekt - he call to Page Controller
I wont that AJAX in JS call to function AddObiekt from class AddObiektForm extends Form

AddObiektForm

<?php
class AddObiektForm extends Form {
		
	function __construct($controller, $name) {
		
		$title = new TextField('Title', 'Tytuł');		
		//OTHER STAFF
		
		$fields = new FieldList(array(
			$title,
			//OTHER STAFF
		));
		
		$validator = new RequiredFields(
            'Title'
			//OTHER STAFF
       	);
		
		$actions = new FieldList($search = new FormAction("AddObiekt", _t("AddObiektForm.ADD", "Dodaj obiekt i przejdź do dodawania zdjęć")));

		parent::__construct($controller, $name, $fields, $actions, $validator);
		
	}

	function forTemplate() {
		return $this -> renderWith(array(
			$this -> class,
			'Form'
		));
	}
	
	public function AddObiekt($data, $form) {
				
		if(Director::is_ajax()){
			return $this -> renderWith("Footer");
		} else { 
		
		//VALIDATE BY PHP
		
		if ($Obiekt) {
			//DO SOMETHING
		} else {
			//DO SOMETHING			
		}
		}
	}

}

JS

function tt() {
			$('#AddObiektForm_AddObiektForm_action_AddObiekt').click(function(e) {
			 	e.preventDefault();
			
			var $form = $("#AddObiektForm_AddObiektForm");
			
				var obiekt_id = $(this).data('obiektid');
				loading_show();
				$.ajax({
					type : "POST",
					url: "ajax/AddObiekt",
					data : $form.serialize()
				}).done(function(msg) {
					$('#sidebarMenuProfil').html(msg);
				}).error(function(msg) {
					alert('Błąd! Proszę spróbować ponownie lub skontaktować się z administratorem');
				});
			});
		}
		$(tt);
