How to make 3 columns in the record view?

My steps:
1. I update array in the record.php: 'templateMeta' =>
        array (
          'maxColumns' => '3',
          'useTabs' => true,
        ),
      ),
2. make manifest.php:
   <?php
    $manifest = array(
        'acceptable_sugar_flavors'  => array('CE','PRO','CORP','ENT','ULT'),
        'acceptable_sugar_versions' => array('exact_matches' => array(),
                         'regex_matches' => array('(.*?)\\.(.*?)\\.(.*?)$')),
        'author'        => 'Nick Gamora',
        'description'        => 'Adding Contacts menu action Links',
        'icon'            => '',
        'is_uninstallable' => true,
        'name'            => 'addContactsActionLink_2016_08_15',
        'published_date'   => '2016-08-15 2016 15:28:04',
        'type'           => 'module',
        'version'       => '1',
    );
   
    $installdefs = array(
        'id' => 'AddingRecordContactsOnly_2016_08_15',
        'copy' => array(
            0 => array(
                'from' => '<basepath>/record.php',
                'to'   => 'custom/modules/Contacts/clients/base/views/record/record.php',
            )
        ),
        
    );
?>
3. make repair & rebuild and go to studio->contacts make layout. But after all changes I do not see any changes.
Does anybody know how to do it correct?
