Inserting to external database

There's a problem in inserting data into external database (joodb tries to insert into Joomla's db). Solution below.
Change:
helpers\joodb.php:511
function saveData($table,&$item) {
$db =& JFactory::getDBO();
controller.php:66
$msg = JoodbHelper::saveData($jb->table,$item);

To:
helpers\joodb.php:511
function saveData($db,$table,&$item) {
// $db =& JFactory::getDBO();
controller.php:66
$joodb_dbo =& $jb->getTableDBO();
$msg = JoodbHelper::saveData($joodb_dbo,$jb->table,$item);
