Answer 1

hi you have to first load view in separate function.this will be your code.
public function index()
{
$this->load->helper('form');
$this->load->view('your view name');
}

Answer 2

i think you need to check that you click to the submit button then the validation
here is the code you need to change in your controller
public function change_pass() {
$this->load->helper('form');
$this->load->library('form_validation');
if ($this->input->post('submit')) {
$this->form_validation->set_rules('new_pass', 'New Password', 'required|matches[cnew_pass]');
$this->form_validation->set_rules('cnew_pass', 'Confirm Password', 'required|matches[new_pass]');
if ($this->form_validation->run() == FALSE) {
die(print_r("Always go here"));
}
}
$this->load->view('change_pass');
}
because of not checking is always false in validation
i think it should help you
