扩展magento核心控制器，但不工作

我正在扩展magento核心控制器，但它不能工作。它不能显示任何错误。我已经为它创建了一个模块。该模块显示在后台的system/configuration/advanced中。我有两个文件控制器等。控制器/AccountController.php:

<?php
require_once Mage::getModuleDir('controllers', 'Mage_Customer').DS.'AccountController.php';
//we need to add this one since Magento wont recognize it automatically
class Inchoo_Coreextended_Frontend_Customer_AccountController extends Mage_Customer_AccountController
{//here, you extended the core controller with our
public function indexAction()
{
parent::indexAction();
//you can always use default functionality
}
public function myactionAction()
{
//my code
//you can write your own methods / actions
}
public function mymethod()
{
//my code
//you can write your own methods
}
public function loginAction()
{
    echo "har har mahadev";
//finally you can write your code that will rewrite the whole core method
//and you can call for your own methods, as you have full control over core controller
}
} 

等/config . xml:

<?xml version="1.0"?>
<config>
    <modules>
        <Inchoo_Coreextended>
            <version>0.2.0</version>
        </Inchoo_Coreextended>
    </modules>
    <frontend>
        <routers>
            <customer>
                <args>
                    <modules>
                        <Inchoo_Coreextended before="Mage_Customer_AccountController">
                            Inchoo_Coreextended_Frontend_Customer_AccountController
                        </Inchoo_Coreextended>
                    </modules>
                </args>
            </customer>
        </routers>
    </frontend>
</config>

当我试图登录时，它显示核心登录文件而不是我的模块登录，也不能显示任何错误和我的模块的值。所以请建议我，我能做些什么。
