I have button in every item in list view when i try save last item no problem but when i try save another item it save data many times

this is my code

public override View GetView(int position, View convertView, ViewGroup parent)

    {

        var item = trans[position];

        View view = convertView;

        if (view == null) // no view to re-use, create new

            view = context.LayoutInflater.Inflate(Resource.Layout.trans_layout, null);

   view.FindViewById<TextView>(Resource.Id.supply_amount_txt).Text = item.amount1;
        view.FindViewById<TextView>(Resource.Id.demand_amount_txt).Text = item.amount2;
        //view.FindViewById<TextView>(Resource.Id.Text3).Text = item.client_code;
        view.FindViewById<TextView>(Resource.Id.supply_cur_txt).Text = item.cur1;
        view.FindViewById<TextView>(Resource.Id.demadn_cur_txt).Text = item.cur2;
        view.FindViewById<TextView>(Resource.Id.rate_txt).Text = item.rate;
        view.FindViewById<TextView>(Resource.Id.ID_txt).Text = item.tran_id;
        view.FindViewById<TextView>(Resource.Id.user_name_txt).Text = item.username;
        view.FindViewById<TextView>(Resource.Id.tran_date_time_txt).Text = item.tran_date ;
        accept_btn = view.FindViewById<Button>(Resource.Id.btn);        
        amo2 = Convert.ToDecimal(item.amount2);
        cu2 = item.cur2;
        amo1 = Convert.ToDecimal(item.amount1);
        cu1 = item.cur1;
        rat = Convert.ToDecimal(item.rate);
        tr_id = Convert.ToInt32(item.tran_id);
        cl_code = item.client_code;
           accept_btn.Click +=delegate {
               myWS.ChekTranIDAsync(Convert.ToInt32(item.tran_id));
               XTran = Convert.ToInt32(Convert.ToInt32(item.tran_id));
               myWS.ChekTranIDCompleted += MyWS_ChekTranIDCompleted;

           };
 


        return view;
      
    }


private void MyWS_ChekTranIDCompleted(object sender, myWS.ChekTranIDCompletedEventArgs e)
    {
        //myWS.accept_tranAsync("123", Convert.ToDecimal(item.amount2), item.cur2, Convert.ToDecimal(item.amount1), item.cur1, Convert.ToDecimal(item.rate), "ابو ليلى", Convert.ToInt32(item.tran_id), item.client_code);
        myWS.accept_tranAsync("123", amo2, cu2, amo1, cu2, rat, "xxx", XTran, cl_code);
        myWS.accept_tranCompleted += MyWS_accept_tranCompleted;


    }

accept_btn.Click +=delegate

This code is executed multiple times as items are recycled for visual display and GetView gets run multiple times for the same view holder. So you need to unsubscribe first.
