How to reload data in UITableview after making second Json call Swift 3

I am making JSON request and if its completed so I am navigating page with JSON data to my table view controller and everything works fine but when I am making second call to load more cells I am not able to reload data and here is the code of my table view controller there I am making second call.

    var listData:[String] = []
    var videoIDData:[String] = []
    var valueKeyData:[String] = []
    var nextPageToken:String?
    var titleNamee:[String] = []
    var videoIDD :[String] = []
    var valueKeyy :[String] = []
    var PrevPageToken:String?



    @IBOutlet weak var tableView: UITableView!


    override func viewDidLoad() {
        super.viewDidLoad()

        tableView.delegate = self
        tableView.dataSource = self
    }

     override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
               return listData.count
    }


    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
      let cell = tableView.dequeueReusableCell(withIdentifier: "VideoCell", for: indexPath) as! VideoTableViewCell
        cell.videoTitle.text = listData[indexPath.row]
        let url = NSURL(string: valueKeyData[indexPath.row])
        let dataaa = NSData(contentsOf: url! as URL)
        let image = UIImage(data: dataaa! as Data)
        cell.videoThumnailImageView.image = image


        if (indexPath.row == listData.count - 1)
        {
            makeGetCall()

        }




     return cell
     }

    func makeGetCall() {
        // Set up the URL request
        var pageToken:String = (pageToken)
        let todoEndpoint: String = "https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&maxResults=50\(pageToken)&playlistId=\(id)_ItOZ8WBF5_SI_SrSN3_F&\(key)"
