ios – Change button title in part of tableview on particular row

I’ve view controller during which there are a number of part of tableview. In part 0 I’ve a number of row . Every row having button named as Add Feedback after I click on on button it pushes me to different view controller having textual content subject when i wrote one thing and press accomplished button then by way of delegate I passes textfield information and set it in button title. However drawback is my button current in all row adjustments worth. I would like solely chosen row in part adjustments its button title. under is my code of first viewcontroller

class MyTabViewController: UIViewController {
var addCommentsValueStore: String = "Add Feedback"
@IBOutlet weak var tabTableView : ContentWrappingTableView!

 @IBAction func addCommentsAction(_ sender: UIButton) {
        guard let nextVC = MyCommentsRouter.getMyCommentsViewScreen() else { return }
        nextVC.passAddCommentsDelegate = self
        self.navigationController?.pushViewController(nextVC, animated: true)

    }

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        if(indexPath.part == 0)
        {
            let indetifier =  "MyTabTableViewCell"
            let cell = tableView.dequeueReusableCell(withIdentifier: indetifier, for: indexPath) as! MyTabTableViewCell
cell.addCommentsButton.setTitle(addCommentsValueStore, for: UIControl.State.regular)
}
return cell
        }

extension MyTabViewController: AddCommentsDelegate{
    func passAddComments(instruction: String) {
        addCommentsValueStore = instruction
        print(addCommentsValueStore)
    }
}
}

under is code of second view controller:

import UIKit
protocol AddCommentsDelegate{
    func passAddComments(instruction: String)
}

class MyCommentsViewController: UIViewController {
    
    @IBOutlet var addCommentsTextField: UITextField!
    var passAddCommentsDelegate: AddCommentsDelegate?
    override func viewDidLoad() {
        tremendous.viewDidLoad()

        
    }
    
    @IBAction func backActionClick(_ sender: UIButton) {

        self.navigationController?.popViewController(animated: true)
    }
    
    @IBAction func DoneActionClick(_ sender: Any) {
        let dataToBeSent = addCommentsTextField.textual content
        self.passAddCommentsDelegate?.passAddComments(instruction: dataToBeSent!)
        self.navigationController?.popViewController(animated: true)
    }
