Set interval in AS 2.0

Hi All,

I want to make call to the fnCall() function everytime fnTrace() is called. Currently only the fnTrace is being called after 2 seconds but the fnCall function is not called following it… any idea why this is happening?

 
class Test {
 public function Test() {
  setInterval(fnTrace, 2000);
 }
 private function fnTrace():Void {
  trace("fnTrace");
  fnCall();
 }
 private function fnCall():Void {
  trace("fnCall");
 }
}
