Controlling/initializing external Class [AS3] - actionscript-3

Question

Before firing away, I know there are many questions here on SO that are quite similar. Yet, none of the solutions given were of any help to me, probably because my case is a little different.
I have a main class which loads an external class (separate .as file). In this external class, there are several objects which have tweens and time events bound to them.
What I want to do, is starting the animations when a certain function is called in my Main class. However, I've tried numerous things to stop and/or reset the animations in the external class, so it will start from the beginning if the required function in Main is called.
Main.as:
package {
//required imports
public class Main extends MovieClip {
var myClass:MyClass = new MyClass; //this is the external class
var button:Button = new Button; //movieclip in the library
public function Main() {
addChild(myClass); //I want to do this here so the objects show from the start
//try 1: myClass.gotoAndStop(1);
//try 2: myClass.stop();
button.addEventListener(MouseEvent.MOUSE_CLICK, playAnimation);
}
function playAnimation (e:MouseEvent) {
//try 1: myClass.gotoAndPlay(1);
//try 2: myClass.start();
//try 3: controlling the startTweening() function in MyClass, I tried different ways
}
}
}
The problem starts in the Main class above. I don't want to animate yet!
MyClass.as:
package {
//required imports
public class MyClass extends MovieClip {
//vars
public function MyClass() {
startTweening();
}
function startTweening() {
//tween event
//calling next function (with use of a TimerEvent) after tween is done. This is repeated several times.
}
}
}
Everything in this class works fine, so that's not the problem.
If this makes any difference, I used TweenMax in MyClass for tweening. I didn't use the timeline in the .fla.
Any help would greatly appreciated!

If you don't want to animate at creation of MyClass remove startTweening(); call from the constructor of MyClass.
Make startTweening(); a public function and call it whenever your need with myClass.startTweening().
Here the MyClass
public class MyClass extends MovieClip {
//vars
public function MyClass() {
}
public function startTweening() {
//tween event
//calling next function (with use of a TimerEvent) after tween is done. This is repeated several times.
}
}
and here the Main class
public class Main extends MovieClip {
var myClass:MyClass;
var button:Button = new Button; //movieclip in the library
public function Main() {
myClass = addChild(new MyClass()) as MyClass;
button.addEventListener(MouseEvent.MOUSE_CLICK, playAnimation);
}
function playAnimation (e:MouseEvent) {
myClass.startTweening();
}
}
