  <p><strong>This is XAML.CS</strong></p>
  
  <pre><code>public partial class MainWindow : Window
  {
      public MainWindow()
      {
          InitializeComponent();
          DataContext = new NoteBoxViewModel();
      }
  }
  </code></pre>
  
  <p><strong>And this is my ModelView</strong></p>
  
  <pre><code>public class NoteBoxViewModel
  {
      public MusicalNotation MusicalNotation { get; set; }
      public ICommand KeyboardHotkeyCommand { get; private set; }
      public bool IsSelected { get; set; }
  
      public NoteBoxViewModel()
      {
          MusicalNotation = new MusicalNotation();
          KeyboardHotkeyCommand = new KeyboardHotkeyCommand(this);
          IsSelected = true;
  
          //Initialization testing
          MusicalNotation.Note = Notes.N1;
          MusicalNotation.Dot = 1;
          MusicalNotation.Octave = -2;
          MusicalNotation.Accidental = Accidentals.Flattened;
      }
  }
  </code></pre>
  
  <p>Even though the model is updated, but the View isn't when input using the <code>InputBindings</code>. Input detection is working properly and the model is updated properly. The converter also works well, otherwise, the initialization testing won't visualize anything too. (The data from initialization testing showed perfectly).</p>
  
  <p>My guess is somewhere on the binding. But I can't find any.</p>
  
  <p>Thanks. </p>
