I think you haven't returned inserted id in model.Try this :

public function save_contract($data){ 
         $insert_id = 0;
       if($this->db->insert("contract", $data)){
        $insert_id = $this->db->insert_id();
        }
        return $insert_id;
    }

CONTROLLER

public function contract_submitted() {

   $data = array(
       'line_of_business_id' => $this->input->post('busi'),
       'Contact_name' => $this->input->post('name')
     );
       $lastID= $this->modal_create_contract->save_contract($data);
       if(!$lastID){
        //Show Error 
        }
       $data['last_id']=$lastID;
       $this->load->view('contract',$data);
    }
