Same Pagination Problem

[eluser]Önder ÖZCAN[/eluser]
I have pagination problem my model is look like :

class Clinic_list extends CI_Model
{
var $limit;
function __construct()
{
// Call the Model constructor
parent::__construct();
$this->load->database();
$this->load->library('pagination');
}

function entries($limit)

{
$query = $this->db->get('v16_listings',$limit);
return $query->result();
}
}
?>

My Controller is :

<?php
class clinics extends CI_Controller
{
var $data;

public function index ()
{

$this->load->model('Clinic_list');
$this->load->helper(array('form', 'url'));
$config['base_url'] = site_url('clinics/index/page/');
$config['total_rows'] = $this->db->count_all('v16_listings');
$config['per_page'] = 20;
$config['last_link'] = 'Son';
$config['first_link'] = 'İlk';
$this->pagination->initialize($config);
$data['_clinicList'] = $this->Clinic_list->entries (30);
$this->load->view('list', $data);
}
}
?>

In view every pagenumber has same data , its look like this :

http://localhost/saglik/index.php/clinics/index/page/
http://localhost/saglik/index.php/clinics/index/page/20
http://localhost/saglik/index.php/clinics/index/page/40

All page number has no data , i also tried with uri segment but it's better to leave it for CI ?
