Normally, you would turn your variable into a get/set function pair.
That is what [Bindable] meta data does for you.
Var _langType:String
Function get langType():String { return _langType}
Function set langType(value:String):void
{
_langType = value;
changeLangTxt();
}

Subject: [flexcoders] Detecting a variable change
Hey everybody!
I've been trying to figure out how to setup a listener to detect a
change in a variable. For instance, lets pretend we have a custom
component with the code below. The langType variable is bound to
another variable in the main application, and I want it to run the
changeLangTxt function whenever the langType variable changes. How do
I do this?
var langType:String = new String("english");
var helloMsg:String;
private function changeLangTxt():void{
if(langType == "spanish"){
helloMsg = "Hola"l
}
if(langType == "english"){
helloMsg = "Hi There"l
}
}
