使用MVVM创建动态控件

我第一次尝试使用mvvm创建一个动态控件。我想动态生成按钮,并在按钮内显示内容。我肯定我错过了一些很容易的事情,但我不知道会是什么。当我运行代码时,界面上没有显示任何内容,尽管我可以看到构造函数中有可用的monitoroc填充。。。

public class CreateAndDisplayViewModel {
    public ObservableCollection<AvailableMonitorBo> AvailableMonitorOC = new ObservableCollection<AvailableMonitorBo>();

    public CreateAndDisplayViewModel() {           
        availableMonitorBo = new AvailableMonitorBo();

        availableMonitorBo.AvailableMonitorLabel = "Label 1";
        AvailableMonitorOC.Add(availableMonitorBo);

        availableMonitorBo.AvailableMonitorLabel = "Label 2";
        AvailableMonitorOC.Add(availableMonitorBo);
    }

    private AvailableMonitorBo availableMonitorBo;
    public AvailableMonitorBo AvailableMonitorBo {
        get { return availableMonitorBo; }
        set {
            availableMonitorBo = value;
        }
    }
}

这是我的模型:

 public class AvailableMonitorBo : INotifyPropertyChanged {

        private string availableMonitorLabel { get; set; }
        public string AvailableMonitorLabel {
            get { return availableMonitorLabel; }
            set {
                availableMonitorLabel = value;
                OnPropertyChanged("AvailableMonitorLabel");
            }
        }

        public event PropertyChangedEventHandler PropertyChanged;
        private void OnPropertyChanged(string propertyName) {
            PropertyChangedEventHandler handler = PropertyChanged;
            if (handler != null) {
                handler(this, new PropertyChangedEventArgs(propertyName));
            }
        }
    }

 <ListView Grid.Row="2" Grid.Column="1"                        
           ItemsSource="{Binding AvailableMonitorOC, Mode=TwoWay}">
                <ListView.ItemTemplate>
                    <DataTemplate>              
                            <StackPanel>                              
                                <Button Content="{Binding AvailableMonitorLabel}"
                                        Width="100"
                                        Height="25"/>
                            </StackPanel>           
                    </DataTemplate>
      </ListView.ItemTemplate>
 </ListView>
