Suppose I have a controller class with a bunch of properties. Each time a property is changed, I would like to update the model. Now also suppose that I use the command pattern to perform model updates. Is it common to use command classes within property get and sets of the controller class or is there a better way?

Here is an example of what I am currently using:

class MyController {
  private int _myInt;
  public int MyInt {
    get { return _myInt; }
    set {
      MyCommand cmd = new MyCommand();
      cmd.Argument = _myInt;
      cmd.Execute();  // Command object updates the model
    }
  } 
}
