Custom Cell - button in cell updates multiple cells

Question

I have a table view with custom cells. The cell consists of two buttons and a label. The buttons is a pluss button, and a minus button. The label is used for counting buttonpresses. When the pluss button is pressed, the label should increment by one, and decrease by one when the minus button is pressed. The problem is that the buttons updates multiple cells. How do I get just that one label in the corresponding cell to update?

Code: Custom Cell File:

import UIKit

class CustomTableViewCell: UITableViewCell {

var counter: Int = 0 {

    didSet {
        counterLabel.text = String(counter)
    }
}

@IBAction func plussButton(_ sender: UIButton)
{
    counter += 1
}
@IBAction func minusButton(_ sender: UIButton)
{
    counter -= 1
}

@IBOutlet weak var nameLabel: UILabel!
@IBOutlet weak var counterLabel: UILabel!
override func awakeFromNib()
{
    super.awakeFromNib()
    // Initialization code
}

override func setSelected(_ selected: Bool, animated: Bool) {
    super.setSelected(selected, animated: animated)
}

}

TableViewController:

import UIKit

class UnderMenyTableViewController: UITableViewController {

var nameArray = ["Cell 1", "Cell 2", "Cell 3", "Cell 4", "Cell 5" ]

override func viewDidLoad() {
    super.viewDidLoad()
}

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

// MARK: - Table view data source

override func numberOfSections(in tableView: UITableView) -> Int {
    // #warning Incomplete implementation, return the number of sections
    return 1
}


override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    // #warning Incomplete implementation, return the number of rows
    return nameArray.count
}


override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "CustomCell", for: indexPath)

    if let customCell = cell as? CustomTableViewCell
    {
        customCell.nameLabel.text = nameArray[indexPath.row]
        customCell.counterLabel.text = String (customCell.counter)

    }


    return cell
}


override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return 200
}

}

Appreciate any help.

P.S: Sorry for the bad formatting on code. This was as good as I could make it.
