After updating tableview alertview becomes unresponsive

[alouanemed]

I have a tableview with several items on whcih each it has an udpate button.When clicked it shows the alert, receive user inputs and reload data of the tableview. The next time I click in the update button, the alert showsup but with no interaction meaninig I can't click in the edittext nor the cancel button. and if clicked outside the alert it keeps showing multiple alerts.

Observable
            .zip(tableView.rx.itemSelected, tableView.rx.modelSelected(CartProductSectionItem.self))
            .bind { indexPath, model in
                switch model {
                case .cartItem(let viewModel) :
                    self.showAlert(with: viewModel.item)
                default:
                    return
                }
            }.disposed(by:rx.disposeBag)
     

The Alert view config.

  func showAlert(with item: CartItem){
        let vm = viewModel as! ViewModel

        let appearance = SCLAlertView.SCLAppearance(
            kTitleFont: Configs.Font.regular(size: 14),
            kTextFont: Configs.Font.regular(size: 14),
            showCloseButton: true, showCircularIcon: false
        )
        
        let alertView = SCLAlertView(appearance: appearance)
        let qty: String = {
            if let qty = item.quantity{
                return String(qty)
            }
            
            return R.string.localizable.cartActionUpdateQty.key.localized()
         }()
        
        let alertViewText = alertView.addTextField(R.string.localizable.cartActionUpdateQtyPrefill.key.localized())
        alertViewText.keyboardType = .numberPad
        alertViewText.text = qty
        _ = alertView.addButton(R.string.localizable.commonActionUpdate.key.localized()) {
            if var qtyValue = alertViewText.text {
                
                if qtyValue.isEmpty{
                    qtyValue = "1"
                }
                
                alertViewText.text = qtyValue
                vm.updateIemQty(with: item.id!, qty: qtyValue)
            }
        }
        
        alertView.showEdit("", subTitle: R.string.localizable.cartActionUpdateQty.key.localized())
    }
