Ajax popup redirects to home page after clicking on "add to cart"

Question

When the add to cart button is clicked, the page is redirected to the home page, and I would like to stay on the current page. I have tried different ways but couldn't accomplish it or getting an error:

public function execute()
    {
        if (!$this->ajaxHelper->isEnabled()) {
            return parent::execute();
        }

        if (!$this->formKeyValidator->validate($this->getRequest())) {
            return $this->resultRedirectFactory->create()->setPath('catalog/product/', ['_current' => true])
        }

        $params = $this->getRequest()->getParams();
        try {
            if (array_key_exists('qty', $params)) {
                $filter = $this->localizedToNormalized;
                $params['qty'] = $filter->filter($params['qty']);
            }

            $product = $this->initProduct();

            /**
             * Check product availability
             */
            if (!$product) {
                return $this->resultRedirectFactory->create()->setPath('/');
            }

            $data = [
                'status' => true,
                'added' => false,
                'messages' => []
            ];

            $result = $this->dataObjectFactory->create()->setData($data);

            $this->_eventManager->dispatch(
                'magepow_ajaxcart_add_before',
                ['product' => $product, 'request' => $this->getRequest(), 'result' => $result]
            );

            if (!$result->getData('status') && empty($messages)) {
                return $this->resultRedirectFactory->create()->setPath('/');
            }

            $this->processAddProduct($result, $product, $params);
            $this->cart->save();

            $this->_eventManager->dispatch(
                'checkout_cart_add_product_complete',
                ['product' => $product, 'request' => $this->getRequest(), 'response' => $this->getResponse()]

                                $this->dataObjectFactory->create()->setProduct($product)
                                : $this->registry->registry('last_added_quote_item');
            return $this->returnResult($resultItem, $this->relatedAdded);
        } catch (\Magento\Framework\Exception\LocalizedException $e) {

            $result['view'] = true;
            // $qty = isset($params['qty']) ? $params['qty'] : 1;

            if( ($product->getTypeId() == 'simple' && !$product->getData('has_options')) || $this->getRequest()->getPost('related_product') ) {

        }
    }
