Form with ajax and javascript problem

I re-create the question with more accurate data (Original question Form with ajax and javascript problem). I have a button in my form that generates a fieldset via ajax. When I try to track this button being clicked with jQuery, it just doesn't see this button.The button id is shown below. I tried to keep track of using just an input as a selector, it still does not work. Javascript is exactly connected, when I click on the submit button, the output is there. Here is the php code.

public function buildForm(array $form, FormStateInterface $form_state) {
    $config = \Drupal::config('pizza_javascript.settings');
    $type_pizza_config = $config->get('Types_pizza');
    $district_config = $config->get('District');
    $sum_order =0;
    foreach ($type_pizza_config as $key=>$name){
      $pizza_type[$name['Price']] = $name['Name'];
    }

    foreach ($district_config as $key=>$name){
      $blocks[$name['Price']] = $name['name'];
    }


$num_pizza = $form_state->get('num_pizza');
if ($num_pizza === NULL) {
  $pizza_field = $form_state->set('num_pizza', 1);
  $num_pizza = 1;
}

$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',
    ],
  ];
}

$form['block'] = [
  '#title' => 'District order',
  '#type' => 'radios',
  '#options' => $blocks,
];


$form['phone'] = [
  '#type' => 'textfield',
  '#title' => $this->t('Phone number'),
  '#description' => $this->t('Example phone number +79261234567, 89261234567, 8(926)123-45-67'),
];

$form['address'] = [
  '#type' => 'textfield',
  '#title' => $this->t('Address order'),
  '#description' => $this->t('Address to order'),
];

$form['all_price'] = [
  '#type' => 'textfield',
  '#title' => $this->t('Price order'),
  '#attributes' => array('readonly' => 'readonly'),
];

$form['pizza_price'] = [
  '#type' => 'textfield',
  '#title' => $this->t('Price pizza'),
  '#attributes' => array('readonly' => 'readonly'),
];




$form['actions']['submit'] = [
  '#type' => 'submit',
  '#value' => $this->t('Submit'),
];


$form['#attached']['library'][] = 'pizza_javascript/pizzaJS';
$form['#attached']['drupalSettings']['data']['blockprice'] = $form_state->getValue('block');
$form['#attached']['drupalSettings']['data']['count_pizza'] = $num_pizza;

return $form;


 }



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();
  }


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

Code javascript.

(function ($, Drupal) {
  Drupal.behaviors.myBehaviour = {
    attach: function (context, settings) {

     $('#edit-pizza-fieldset-general-actions-add-pizza',context).on('click',function (){
       console.log('Hello world!!!');
     })
      $('input').on('click',function (){
       console.log('Hello world!!!');
     })

    }

  }

})(jQuery, Drupal);

Since I keep track of input elements, the button generating fields must display, but this does not happen. Please help me understand what the problem is. Sorry for my english, i used google translated
