wpf用通知属性更新动态创建的按钮显示文本

1.自定义通知类

 public class NotifyBase : INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged;

        public void NotifyChanged([CallerMemberName] string propName = "")
        {
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propName));
        }
    }

2 .创建动态按钮

  Random random = new Random();
            for (int i = 0; i < 3; i++)
            {
                lstBtn.Add(new DataGridItemModel2 { Name = "btn测试-" + i.ToString("00"), Age = random.Next(18, 90), Value = random.Next(30, 120).ToString() });
            }
            foreach (var actor in lstBtn)
            {
                CreateDynamicButton(actor.Name, actor.Age);
            }
public void CreateDynamicButton(string btnText, int actIndepth)
        {
            Button btn = new Button();
            btn.Content = btnText;
            btn.Margin = new Thickness(3, 0, 0, 0);
            btn.Padding = new Thickness(3, 0, 0, 0);
            //btn.GradientMode = System.Drawing.Drawing2D.LinearGradientMode.Vertical;
            //btn.BackColor = Color.FromKnownColor(KnownColor.Control);          
            btn.Cursor = Cursors.Hand;
            btn.Height = 70;
            btn.Width = 300;
            btn.Tag = actIndepth;
            grid.Children.Add(btn);
        }

   
    public class DataGridItemModel2:NotifyBase
    {
        private string _name;

        public string Name
        {
            get { return _name; }
            set { _name = value; this.NotifyChanged(); }
        }


        private int _age;

        public int Age
        {
            get { return _age; }
            set { _age = value; this.NotifyChanged(); }
        }


        public string Value
        {
            get;
            set;
        }
    }
    }

3.试图更改动态创建的按钮显示文本，界面不能更
MainWindow.lstBtn[0].Name = "test";

用异步线程尝试定位按钮name给name.content赋值

我xaml是这样写的，具体还不知怎样完成这个绑定。。。

<UniformGrid Margin="10" Name="grid">
        </UniformGrid>
