codeigniter update db with custom_result_object() - php

Question

I got a codeigniter custom_result_object with this:
$user = $this->CI->db->get_where('users', array('email' => $email), 1)->custom_row_object(0,'entities\User');
and everything looks fine. I can update values with my setters.
Before I'm going to save i check my values with:
die(print_r($user));
and the values are correct.
I put my object in my update method.
$this->CI->db->update('users', $user, "id = ".$user->getId());
But the db is not updating. Am I missing something?
Thx!
EDIT:
So by using CI native db-method i can use:
public function save($user)
{
if($user->getId() == NULL){
$this->CI->db->insert('users', $user);
}else{
$this->CI->db->update('users', $user, "id = ".$user->getId());
}
}
Edit 2:
After some more checking I can see that it's not setting variables that are protected. CI is able to get the object through getters and setters but not able to save back to DB?

public function saveData($tbl,$data,$update = false,$previewStr = false){
$set_str = "NO_QUOTES()";
if(isset($data[$set_str])){
foreach($data[$set_str] as $set_key => $set_value){
$this->db->set($set_key, $set_value, FALSE);
}
unset($data[$set_str]);
}
if(isset($update[$set_str])){
foreach($update[$set_str] as $whr_key => $whr_value){
$this->db->where($whr_key." ".$whr_value,NULL,false);
}
unset($update[$set_str]);
if(is_array($update) and count($update) <= 0){
$update = true;
}
}
if($update == false){
$this->db->insert($tbl, $data);
if($previewStr){
return $this->db->last_query();
}else{
return $this->db->insert_id();
}
}else{
$result = NULL;
if(!is_array($update)){
if(is_array($data) and count($data) > 0){
foreach($data as $field => $value){
$this->db->set($field, $value);
}
}
$result = $this->db->update($tbl);
}else{
$result = $this->db->update($tbl, $data,$update);
}
if($previewStr){
return $this->db->last_query();
}else{
return $result;
}
}
}
public function delData($tbl = false,$where = array()){
if($tbl !== false){
return $this->db->delete($tbl, $where);
}else{
return false;
}
}
public function simpleQuery($query,$return_array = false,$return_single = false)
{
$ac = $this->db->query($query);
if($return_array === false){
return $ac;
}else{
if($return_single === false){
return $ac->result_array();
}else{
return $ac->row_array();
}
}
}
