The AJAX function

add_action('wp_ajax_my_options_reset', 'reset_default_options');
function reset_default_options() {
  // the nonce name here needs to be the same as the
  // the nonce name you created when enqueuing the script
  if (!wp_verify_nonce($_POST['nonce'], 'my_options_reset_nonce')) {
    echo false;
    exit;
  }
  // reset values in a repeater
  // this needs to be the name of the repeater
  // you want to clear
  $repeater = 'repeater_name';
  // list of sub field in repeater
  $subfields = array(
    'campo_teste',
  );
  // list of other fields to be reset
  // this is a list of other fields that
  // are not part of a repeater
  $fields = array(
    'campo_texto',
  );
  $repeater_count = intval(get_option('options_'.$repeater, 0));
  for ($i=0; $i<$repeater_count; $i++) {
    foreach ($subfields as $subfield) {
      delete_option('options_'.$repeater.'_'.$i.'_'.$subfield);
      delete_option('_options_'.$repeater.'_'.$i.'_'.$subfield);
    }
  }
  delete_option('options_'.$repeater);
  delete_option('_options_'.$repeater);
  foreach ($fields as $field) {
    delete_option('options_'.$repeater);
    delete_option('_options_'.$repeater);
  }
  echo true;
