Add Category attributes for second time using upgrade

[abhilash123]

I need to add custom attributes for category. I have added couple of custom attributes for category using the install script. Now i need to add another couple of attributes. I have tried with the following code but it didn't worked

public function upgrade(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
{
/** @var \Magento\Catalog\Setup\CategorySetup $categorySetup */
$categorySetup = $this->categorySetupFactory->create(['setup' => $setup]);

    $entityTypeId = $categorySetup->getEntityTypeId(\Magento\Catalog\Model\Category::ENTITY);
    $attributeSetId = $categorySetup->getDefaultAttributeSetId($entityTypeId);
    $testAttributeGroupId = $categorySetup->getAttributeGroupId($entityTypeId, $attributeSetId, 'Test');

    $categorySetup->addAttribute(
        \Magento\Catalog\Model\Category::ENTITY, 'custom_link', [
            'type' => 'text',
            'label' => 'Custom Link',
            'input' => 'text',
            'required' => false,
            'sort_order' => 30,
            'global' => \Magento\Catalog\Model\Resource\Eav\Attribute::SCOPE_STORE,
            'is_html_allowed_on_front' => true,
            'group' => 'Test',
            'default' => ''
        ]
    );
    $categorySetup->addAttribute(
        \Magento\Catalog\Model\Category::ENTITY, 'display_shop_all', [
            'type' => 'int',
            'label' => 'Display Shop All',
            'input' => 'select',
            'source' => 'Magento\Eav\Model\Entity\Attribute\Source\Boolean',
            'required' => false,
            'sort_order' => 40,
            'global' => \Magento\Catalog\Model\Resource\Eav\Attribute::SCOPE_STORE,
            'group' => 'Test',
        ]
    );

    $categorySetup->addAttributeToGroup(
        $entityTypeId,
        $attributeSetId,
        $testAttributeGroupId,
        'custom_link',
        30
    );
    $categorySetup->addAttributeToGroup(
        $entityTypeId,
        $attributeSetId,
        $testAttributeGroupId,
        'display_shop_all',
        40
    );

}

I have made this working. The following are the steps.
You need to create the class UpgradeData which implements UpgradeDataInterface (Magento\Framework\Setup\UpgradeDataInterface) then add the above piece of code.

It worked like charm..
