Ok, I did it commenting these lines in render function in syntax.php, but maybe there are a better solution.
if(isset($_POST['bureaucracy']) && checkSecurityToken() && $_POST['bureaucracy']['$$id'] == $this->form_id) {
$success = $this->_handlepost($data);
//if($success !== false) {
//$R->doc .= '<div class="bureaucracy__plugin" id="scroll__here">' . $success . '</div>';
//return true;
//}
}
