Problem extending library

[eluser]Sumeet Kashyap[/eluser]
Hi folks!
There is a problem extending my library on server but i is working perfectly fine on local wamp. I am trying to extend the CI pagination library with my own library using the following code:

Code:

class my_pagination extends CI_Pagination {
    function __construct($params = array())
    {
        parent::__construct($params);
    }

    function initialize_js_function($jsFunction = array())
    {
          // Code here
    }
}

I have set the config param as:

Code:

$config['subclass_prefix'] = 'my_';

The server is running linux where i know the file system is case sensitive and so i have named the library as "my_pagination.php". I am loading the library as it should using

Code:

$this->load->library('pagination');

but it seems to having some problem and giving me the error:
Fatal error: Call to undefined method CI_Pagination::initialize_js_function()

Please help,
Thanks in advance :red:
