        $this->_formScripts[] = "
            function toggleEditor() {
                if (tinyMCE.getInstanceById('overview') == null) {
                    tinyMCE.execCommand('mceAddControl', false, 'overview');

Here is my save.php controller

Vendor\Module\Controller\Adminhtml\Module;

class Save extends \Magento\Backend\App\Action
{
            var $sliderFactory;


    public function __construct(
        \Magento\Backend\App\Action\Context $context,
        \FME\ProductSliders\Model\ProductSlidersFactory $sliderFactory
    ) {
        parent::__construct($context);
        $this->sliderFactory = $sliderFactory;
    }


    public function execute()
    {
        $data = $this->getRequest()->getPostValue();
        if (!$data) {

            $this->_redirect('fme_productsliders/productsliders/edit');
            return;
        }
        try {
            $rowData = $this->sliderFactory->create();
            $rowData->setData($data);
            if (isset($data['slider_id'])) {
                $rowData->setEntityId($data['slider_id']);
            }
            $rowData->save();
            $this->messageManager->addSuccess(__('Row data has been successfully saved.'));
        } catch (\Exception $e) {
            $this->messageManager->addError(__($e->getMessage()));
        }
        $this->_redirect('fme_productsliders/productsliders/index');
    }

    /**
     * @return bool
     */
    protected function _isAllowed()
    {
        return $this->_authorization->isAllowed('FME_ProductSliders::save');
    }
