Form with ajax and javascript problem

i have a problem with a form using ajax elements. I have a button in my form that generates a fieldset with fields via ajax. When I try to track this button being clicked with jQuery, it just doesn’t see this button. I tried to keep track of using just an input as a selector, it still does not work. Help please, thanks in advance for help.

    public function buildForm(array $form, FormStateInterface $form_state) {
 $form('pizza_fieldset_general') = (
      '#type' => 'fieldset',
      '#tree' => TRUE,
      '#title' => $this->t('Orders'),
      '#prefix' => '<div id="pizza-fieldset-general-wrapper">',
      '#suffix' => '</div>',
    );
    for ($i = 0; $i < $num_pizza; $i++) {
      $form('pizza_fieldset_general')('pizza_fieldset')($i) = (
        '#type' => 'fieldset',
        '#tree' => TRUE,
        '#title' => $this->t('Pizza to order'),
      );
      $form('pizza_fieldset_general')('pizza_fieldset')($i)('name') = (
        '#type' => 'select',
        '#title' => $this->t('Type pizza'),
        '#tree' => TRUE,
        '#options' => $pizza_type,
        '#default_value' => '940',
        '#attributes' => ('id' => 'select-pizza-'.$i),
      );

      $form('pizza_fieldset_general')('pizza_fieldset')($i)('count') = (
        '#type' => 'select',
        '#title' => $this->t('Count pizza'),
        '#tree' => TRUE,
        '#options' => range(0, 10),
        '#attributes' => ('id' => 'select-count-'.$i),
      );
    }

    $form('pizza_fieldset_general')('actions') = (
      '#type' => 'actions',
    );


    $form('pizza_fieldset_general')('actions')('add_pizza') = (
      '#type' => 'submit',
      '#value' => $this->t('Add one pizza'),
      '#submit' => ('::addOnePizza'),
      '#ajax' => (
        'callback' => '::addmorepizzaCallback',
        'wrapper' => 'pizza-fieldset-general-wrapper',
      ),
    );
    if ($num_pizza > 1) {
      $form('pizza_fieldset_general')('actions')('remove_pizza') = (
        '#type' => 'submit',
        '#value' => $this->t('Remove one'),
        '#submit' => ('::removeCallback'),
        '#ajax' => (
          'callback' => '::addmorepizzaCallback',
          'wrapper' => 'pizza-fieldset-general-wrapper',
        ),
      );
    }
    }



public function addmorepizzaCallback(array &$form, FormStateInterface $form_state) {
    return $form('pizza_fieldset_general');
  }



  public function addOnePizza(array &$form, FormStateInterface $form_state) {
    $pizza_field = $form_state->get('num_pizza');
    $add_button = $pizza_field + 1;
    $form_state->set('num_pizza', $add_button);
    $form_state->setRebuild();
  }
