User Registration - I need Help

am registering users via csv file. I get user details, then save them in the usual users table using the JUser class. What is not working are extra columns I have. I've created them in the db already. My code is as below

                $pass = 'xxxxxxx'; //default
                $data = array(
                      "name"=>$allnew[$i]->name,
                      "username"=>$allnew[$i]->username,
                      "password"=>$pass,
                      "password2"=>$pass,
                      "email"=>$allnew[$i]->email,
                      "telephone"=>$allnew[$i]->telephone,
                      "test"=>strtolower($allnew[$i]->test),
                      "test1"=>$allnew[$i]->test1,
                      "gid"=>18,
                      "usertype"=>$newUsertype
                );
                $userr = new JUser;
                if(!$userr->bind($data)) {
                    throw new Exception("Could not bind data. Error: " . $userr->getError());
                }
                $userr->set('id', 0);
                $userr->set('usertype', $newUsertype);
                $userr->set('gid', $authorize->get_group_id( '', $newUsertype, 'ARO' ));
                $date =& JFactory::getDate();
                $userr->set('registerDate', $date->toMySQL());
                $userr->set('leavedays', $data['leavedays']);
                $useractivation = $usersConfig->get( 'useractivation' );
                if ($useractivation == '1')
                    {
                        jimport('joomla.user.helper');
                        $userr->set('activation',$pass );
                        $userr->set('block', '1');
                    }
                if($userr->save()) {
                    echo ' Success';
                } else { echo 'error'; }

please help. test and test1 are not being saved and I can't tell why. both columns exist in the database.
