Collision detection with Corey Oneil collision List need advice

[LostTemplar]

Hi, I'm currently stuck for a school project. I use the Corey Oneil Dectetion Kit.

On my stage, I have a decagon. I have a button who add circles in the decagon.

These circles go randomly in a random direction with an ENTER_FRAME and I want them to bounce on the decagon borders and stay in it.

this is my collision function. As you can see I call the method limiteBalle() for the object1 wich is my class Balle ( my circles)

public function verifierColision(pEvt:Event)

{

     var collisions:Array = listeDeCollision.checkCollisions();

     if(collisions.length > 0)

{

for (var i:int; i < collisions.length; i++)

{

     Balle(collisions.object1.limiteBalle());

     trace("toucher");

}

}

In my other Class :  Balle.as, I call an eventListener in the function limiteBalle() but the circles only bounce one time before  going out of the decagon

public var nombreX:Number = randomRange(-15,15);

public var nombreY:Number = randomRange(15,-15);

public function Balle()

{

     this.addEventListener(Event.ADDED_TO_STAGE,bougeBalle);

}

public function bougeBalle(pEvt:Event)

{

     this.addEventListener(Event.ENTER_FRAME,bougeBalle);

     this.x +=  nombreX;

     this.y +=  nombreY;

}

public function limiteBalle()

{

     this.addEventListener(Event.ENTER_FRAME,rebondBalle);

}

public function rebondBalle(pEvt:Event)

{

      if (this.x < 0)

     {

     this.x +=  nombreX;

     rebond1();

     }

      if (this.y < 0)

     {

     this.y +=  nombreY;

     rebond1();

     }

      if (this.x < 0)

     {

     this.x +=  nombreX;

     rebond2();

     }

      if (this.x < 0)

     {

     this.y +=  nombreY;

     rebond2();

     }

public function rebond1(){

this.x +=  nombreX;

this.y +=  nombreY;

}

public function rebond2(){

this.x -=  nombreX;

this.y -=  nombreY;

}

}

Thanks

fix this:

public function Balle()

{

     this.addEventListener(Event.ADDED_TO_STAGE,bougeBalle);

}

public function bougeBalle(pEvt:Event)

{

     this.addEventListener(Event.ENTER_FRAME,bougeBalle);

     this.x +=  nombreX;

     this.y +=  nombreY;

}

to

public function Balle()

{

     this.addEventListener(Event.ADDED_TO_STAGE,init);

}

private function init(e:Event):void{

   this.addEventListener(Event.ENTER_FRAME,bougeBalle);

}

public function bougeBalle(pEvt:Event)

{

     this.x +=  nombreX;

     this.y +=  nombreY;

}

then explain what problem you see

my circle is only bouncing one time on the border of the decagon and then pass throught it.

what's this do:

Balle(collisions.object1.limiteBalle());
