It makes getters and setters. In the setter, it dispatches a PropertyChangeEvent. If you want to see the actual code generated, add "-keep-generated-actionscript=true" to your compiler options. Here is a sample of some of my code when I include the aforementioned option.
* generated bindable wrapper for property includeElite (public)
* - generated setter
* - generated getter
* - original public var 'includeElite' moved to '_73901365includeElite'
public function get includeElite():Boolean
public function set includeElite(value:Boolean):void
var oldValue:Object = this._73901365includeElite;
if (oldValue !== value)
this._73901365includeElite = value;
this.dispatchEvent(mx.events.PropertyChangeEvent.createUpdateEvent(this, "includeElite", oldValue, value));
Use -keep-generated-actionscript and you will see the code that is
