Try my following code, hope this will works.

function bayerkol_callback($ajax) {
  if ($ajax) {
     global $user;

     ctools_include('node.pages', 'node', '');
     ctools_include('modal');
     ctools_include('ajax');

     $node = (object) array(
         'uid' => $user->uid,
         'name' => (isset($user->name) ? $user->name : ''),
         'type' => 'article',
         'language' => LANGUAGE_NONE,
     );

     $form_state = array(
         'ajax' => TRUE,
         'title' => t('Add Event'),
     );

     $form_state['build_info']['args'] = array($node);

     $output = ctools_modal_form_wrapper('bayerkol_form', $form_state);

     // This means the form has been exectued
     if (!empty($form_state['executed'])) {
         $output = array();
         // Close the modal
         $output[] = ctools_modal_command_dismiss();
     }

    print ajax_render($output);
    exit;
  }else {
         return drupal_get_form('event_calendar_node_form');
   }
  }

In above code no need to call bayerkol_form function. make sure your node form is correct example: for article use {article_node_form}
