problem with Multitouch.inputMode in AS3

Hi everybody.

My problem is that when i write 2 differents "Multitouch.inputMode" in my script (for Androïd), in every case, only the first written works.... How can i do to conserve the two behaviors ? (i'm a new french user of AS3...)

An example of my very simple AS3 code

stop();

Multitouch.inputMode = MultitouchInputMode.GESTURE;

oc_carte.addEventListener(TransformGestureEvent.GESTURE_PAN, fl_PanHandler_5);

function fl_PanHandler_5(event:TransformGestureEvent):void

{

    event.currentTarget.x += event.offsetX;

    event.currentTarget.y += event.offsetY;

}

oc_carte.addEventListener(TransformGestureEvent.GESTURE_ZOOM, fl_ZoomHandler_2);

function fl_ZoomHandler_2(event:TransformGestureEvent):void

{

    oc_carte.scaleX *= event.scaleX;

    oc_carte.scaleY *= event.scaleY;

}

Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;

oc_retourmenu.addEventListener(TouchEvent.TOUCH_TAP, fl_TapHandler_1);

function fl_TapHandler_1(event:TouchEvent):void

{

    MovieClip(this.root).gotoAndPlay(1, "Séquence 2");

}
