Controller is firing but I can't get the $_GET

I managed to see the message being sent in the network debugger. It is:
http://localhost/Subit_backend/register%....com%22%7D

The status (from the network tab in the chrome debugger) is (pending). Is this because it was never recvd by Subit_backend?



   class Subit_backend extends CI_Controller
   {

       public function __construct()
       {
       parent::__construct();

       $this->load->database();
       $this->load->helper('url', 'input' );
         }


       public function register()
      {
      if (isset($_GET["email"])) {
          $this->db->db_select("employees");
        }
      }
   }
