I need to put some ajax buttons on each row of table.

My theme looks like this:

/**  * Implements hook_theme().  */ function application_wizard_theme($existing, $type, $theme, $path) {   return array(     'application_wizard_table' => array(       'render element' => 'element'     ),   ); }  function theme_application_wizard_table($vars) {   extract($vars);   $header = $element['#header'];   $header['operations'] = array('data' => t('Operations'));    $rows = $element['#rows'];    foreach ($rows as $key => $row) {     foreach ($row as $fieldKey => $field) {       $fieldValue = $field[$fieldKey][LANGUAGE_NONE]['0']['value'];       $rows[$key][$fieldKey] = $fieldValue;     }      $operations = array();     $operations['delete'] = array(       '#type' => 'submit',       '#value' => t('Delete'),       '#ajax' => array(         'wrapper' => 'wizard-form-wrapper',         'callback' => 'application_wizard_callback'       ),     );      $rows[$key]['operations'] = drupal_render($operations);   }    return theme('table', array(     'header' => $header,      'rows' => $rows,     )   ); }  function application_wizard_callback($form, $form_state) {   return $form; }  function application_wizard_submit($form, &$form_state) {   if ($form_state['triggering_element']['#value'] == t('Delete')) {     dpm($form_state['triggering_element']);   } } 

There is no action when I click on generated Delete buttons. In other words, buttons doesn’t work.

I have no clue what I am doing wrong so I was hoping someone could tell me thank you in advance.
