Controller delete function error

Question

I am getting an error in my code and don't know why. Here is the error :

Fatal error: Call to undefined method Display::index() in

Here is the controller part that causes the error:

 function delete(){
     $this->load->model('display_model');
     $this->display_model->delete_row();
     $this->index();

 }

and model part if needed just in case:

function delete_row()
          {
             $this->db->where('QID', $this->uri->segment(3));
             $this->db->delete('tblquestions');
          }

Instead you can do like below:

function delete(){
     $this->load->model('display_model');
     $this->display_model->delete_row();
     redirect('/controllerName/', 'refresh');
 }

The benefit of redirect is that you can set some message to user that you completed or failed to do action by passing some id.

function delete(){
     $this->load->model('display_model');
     $this->display_model->delete_row();
     redirect('/controllerName/index/1', 'refresh');
 }

just put "$this->output->enable_profiler(TRUE);" in your controller so that it will print the query at the bottom of the page(in browser).
