Facebook native Ads are not clickable again in UITableView Cells after scroll

I have implemented facebook native Ads in UITableView, for first 1-2 times it clickable but when I scroll tableview and come again back to the same cell, now Ads are not clicking, I am using swift 3.2 Below is the cell implementation.

let ad = adsManager.nextNativeAd
let cell = self.tableHome.dequeueReusableCell(withIdentifier: "HomeAdsTableViewCell", for: indexPath) as! HomeAdsTableViewCell
cell.message.text = ad?.body
cell.title.text = ad?.title
cell.callToActionButton.setTitle(ad?.callToAction, for: .normal)

if let pic = ad?.coverImage {
    cell.postImage.setImageWithIndicator(imageUrl:pic.url.absoluteString)
}

ad?.registerView(forInteraction: cell.postView, with: self)
cell.selectionStyle=UITableViewCellSelectionStyle.none

return cell
