<p>Ans:<br>
ChangeWatcher: The ChangeWatcher class watches for change an object. Note that
the properties that can be watched by the ChangeWatcher must be bindable - hence
the connection to binding. There is another static function on ChangeWatcher
that is worth a mention, it is watch. This is the bread and butter function of
the class.<br>
ChangeWatcher.watch(myCoolObject, "coolProperty",function(e:Event):void { trace(e.target);
})<br>
<br>
bindingutils.bindproperty: To achieve simple data-binding in an application, it
is often enough to mark the target variables as "bindable". However, if these
variables are member variables of a class that you've instantiated, we must do
more than simply mark them as "bindable". We must use the bindProperty()
function provided by the BindingUtils class.<br>
BindingUtils.bindProperty(dogNameText, "text", myDog, "name");<br>
