Magento 1.7 – Extending Cart Controller for Specific Actions

I am trying to extend /checkout/cart/. I added "dumbAction" to test ensure the extension worked and /checkout/cart/dumb does work. However, when I access /checkout/cart I do not see any changes.

    <?php

    /*
     * To change this license header, choose License Headers in Project Properties.
     * To change this template file, choose Tools | Templates
     * and open the template in the editor.
     */

    require_once 'Mage/Checkout/controllers/CartController.php';

    class AimlessMedia_CheckoutActions_CartController extends Mage_Checkout_CartController
    /* the only reason this is extending the cart controller
     * is because I copied AimlessMedia_CheckoutDiscountOption and it
     * easier to just ride out the already programmed code
     */ {
        /**
         * Initialize coupon
         */
        public function dumbAction() {
            echo 'test indexAction';
        }
        public function indexAction() {
            echo ('test indexAction');
            parent::addAction();
        }
    }

Resolution

Modified Config.xml to:

                <modules>
                    <CheckoutActions before="Mage_Checkout">AimlessMedia_CheckoutActions</CheckoutActions>
                </modules>
