Get Custom Attribute in Category – Magento Guide

i am using magento enterprise edition, i have created a module to add custom attributes to the categories , the attributes are visible in adminhtml and they are saved propertly but when i try to retrieve the category on frontend, it doesnot contain the attributes i just created and i alredy reindex all but nothing, the problem is magento enterprise because i tried in magento community and works fine, here is my code

   $installer = Mage::getResourceModel('catalog/setup','catalog_setup');
    $installer->startSetup();
    $label="whatever";

 $installer->addAttribute('catalog_category', $label, array(
                   'type' => 'int',
                   'label' => $label,
                   'input' => 'select',
                   'source'  => 'eav/entity_attribute_source_boolean',
                   'global' => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL,
                   'visible' => true,
                   'required' => false,
                   'default' => '0',
                   "visible_on_front"  => true,
                   'group' => 'filter9',
               ));

And this is front end where i am trying to reindex data and retrieve the category:

 $categories = Mage::getModel('catalog/category')->getCollection()
->addAttributeToSelect('*');
 $process = Mage::getModel('index/process')->load(5);   $process->reindexAll();
  $process = Mage::getModel('index/process')->load(6);    $process->reindexAll();
 foreach ($categories as $category) {



$cat = Mage::getModel("catalog/category")->load($category->getId());
if($cat->getData('entity_id')=='7'){
        var_dump($cat->getData()); // all but my attribute
        var_dump($cat); // my attribute is not there :(

        var_dump($cat->getName()); // My  Category Name
     }

 }

Any suggestion is welcome, please help me!!
