title: binding a label to a property
body: <p>I'd like to bind a label to a property of a class and tried this:</p>
  
  <pre><code>public class Test
  {
      public string Name { get; set; }
  }
  
  Test test = new Test () { Name = "abc" };
  label.DataBindings.Add ("Text", test, "Name");
  </code></pre>
  
  <p>This shows "abc" at the label. If I change the Name property after the data binding, the label does not reflect the new value. What's wrong?</p>
