Magento2 Setup Script Not Loaded – Troubleshooting and Fixes

I've been banging my head for a few hours now. I have setup a small Magento 2 module. It is enabled everything is working except the Setup scripts never run. Actually from my diagnosis right now, they aren't even required in the setup:upgrade process.

If it could be of any help here are the module configuration files:

registration.php:

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'Wizbusiness_CustomerSubscriptions',
    __DIR__
);

etc/module.xml:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
                <module name="Wizbusiness_CustomerSubscriptions" setup_version="0.0.9" />
</config>

Setup/InstallData.php:

<?php
namespace Wizbusiness\CustomerSubscriptions\Setup;

use Magento\Framework\Module\Setup\Migration;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;

class InstallData implements InstallDataInterface
{
    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        $setup->startSetup();

        $customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);

        /** @var CustomerSetup $customerSetup */
        $customerSetup->addAttribute(
            Customer::ENTITY,
            'subscribedtags',
            [
                'type' => 'text',
                'input' => 'multiselect',
                'backend' => 'Magento\Eav\Model\Entity\Attribute\Backend\ArrayBackend',
                'global' => \Magento\Catalog\Model\Resource\Eav\Attribute::SCOPE_GLOBAL,
                'label' => 'Subscribed Tags',
                'required' => 0,
                'system' => 0, // <-- important, otherwise values aren't saved.
                               // @see Magento\Customer\Model\Metadata\CustomerMetadata::getCustomAttributesMetadata()
                'position' => 100,
                'filterable' => true,
                'option' => [ 'values' => ['Test', 'Test2', 'Test3' ] ]
            ]
        );

        $used_in_forms=array();
        $used_in_forms[]="adminhtml_customer";
        $used_in_forms[]="checkout_register";
        $used_in_forms[]="customer_account_create";
        $used_in_forms[]="customer_account_edit";
        $used_in_forms[]="adminhtml_checkout";
        $customerSetup->getEavConfig()->getAttribute('customer', 'subscribedtags')
            ->setData('used_in_forms', [$used_in_forms])
            ->setData("is_used_for_customer_segment", true)
            ->setData("is_user_defined", 1)
            ->save();
        $setup->endSetup();
    }
}

Also a smaller test in Setup/Recurring.php:

<?php
namespace Wizbusiness\CustomerSubscriptions\Setup;

use Magento\Framework\Setup\InstallSchemaInterface;
use Magento\Framework\Setup\SchemaSetupInterface;
use Magento\Framework\Setup\ModuleContextInterface;

class Recurring implements InstallSchemaInterface {

    protected $logger;

    public function __construct(
        \Psr\Log\LoggerInterface $loggerInterface
    ) {
        $this->logger = $loggerInterface;
    }

    public function install( SchemaSetupInterface $setup, ModuleContextInterface $context ) {
        touch("<path here>/recurring.txt");
        $this->logger->debug('This is running');
    }
}

If anybody knows what's up, please help me!
