[AS2] onEnterFrame Problem on an .as file

Hello

I think it could be simple to solve but i cant figure it out because im just starting with classes, so im posting here. The problem is that i want to excute a function on a class file every frame, but it just appears once when in test it. Here are the codes (i made a simple example to focus on the problem):

Class .as


class Repeat extends MovieClip {
    var Container:MovieClip;
    function Repeat (Target:MovieClip){
        this.Container = Target;
    }
    function Speak (){
        this.Container.onEnterFrame = this.Words();
    }
    function Words (){
        trace ("Bla bla bla bla")
    }
}


.fla code

 
var Holder:MovieClip = this.createEmptyMovieClip ("Holder",this.getNextHighestDepth());
var myRepeat = new Repeat(Holder);
myRepeat.Speak();

Any help will be appreciated
Thanks in advance=)
