jQuery UI Auto Complete Help

Hello Community,

A weird code behavior is faced. It might be coding problem. Here is a scenerio.

I am trying to implement auto complete feature using jQuery UI and returning proper json encoded data. Following is a controller call.

Code:

/*Following code works, if I put exit in the end*/
function get_products(){

       if (isset($_GET['name'])){
           $q = strtolower($_GET['name']);
           $this->Product_model->get_product($q);
           exit;
       }

/*Following code does not work because it does not have exit in end*/
function get_products(){

       if (isset($_GET['name'])){
           $q = strtolower($_GET['name']);
           $this->Product_model->get_product($q);

       }

I want to know the difference, it is probably it looks for the view or is there something special which I am missing ?

Regards,
Sam
