The OP is using a public setter function to implement his public property, instead of a public variable, which is fine, even prefereable.
And the trace shows that his setter is being called, but with the incorrect value. I suspect a timing issue, but can't think of a solution. Perhaps an invalidate of some kind?

AFAIK (I am a newb to flex) to be able to set a property in a custom component, that property must be public. When Flex compiles the application, mxml components are compiled into actionscript classes so to modify the property it must be available to outside classes. Making it private denies other objects from doing so. Also, you are running your init method on initialize. I think you meant for it to run on creationcomplete (This is why you are getting NaN). I have modified your code to reflect the above: Application: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:com="*" xmlns:mx="http://www.adobe.com/2006/mxml <http://www.adobe.com/2006/mxml> " layout="absolute"> <mx:TextInput text="100" id="tiTitulo" width="200" maxChars="100" change="descCounter.countChars(tiTitulo.length)"/> <com:CharCounter y="30" id="descCounter" _maxChars="{tiTitulo.maxChars}" /> </mx:Application> Custom Component: <?xml version="1.0" encoding="utf-8"?> <mx:Label xmlns:mx="http://www.adobe.com/2006/mxml <http://www.adobe.com/2006/mxml> " creationComplete="init()" > <mx:Script> <![CDATA[ [Bindable] private var _charNumber:Number; [Bindable] public var _maxChars:Number; private function init():void { _charNumber = _maxChars; this.text = this._charNumber.toString(); } public function set maxChars(value:Number):void { _maxChars = value; trace("MAXCHARS" + _maxChars); } public function get maxChars():Number { return _maxChars; } public function countChars(value:Number):void { var maxChars:Number = _maxChars; _charNumber = maxChars - value; this.text = _charNumber.toString(); } ]]> </mx:Script> </mx:Label>
