Recycling Class objects not setting variables for Typed Group

[Shaun Michael K. Stone]

/**

 * 

 * @param levelId

 * @param gameObjects

 */

public function buildLevelObjectsFromJson(levelId:UInt = 0, gameObjects:Array<LevelObjects>):Void

{

logLevelBuild(levelId);

this.levelId = levelId;

for (obj in gameObjects)

{

trace('adding: ' + obj.id + ' to game objects pool');

var gameObj:GameObject = this.factory.get(

obj.id,

obj.type,

obj.typeId,

obj.delayBefore,

obj.delayAfter,

obj.speed,

obj.xPos,

obj.yPos

);

gameObj.setSpriteAnimations(textureAtlas);

setStartingPosition(gameObj, obj.xPos, obj.yPos);

setDelays(gameObj, obj.delayBefore, obj.delayAfter);

gameObj.setBounds(this.bounds);

gameObj.kill();

this.add(gameObj);

}

}

public function start():Void

{

this.timer.start(FlxRandom.intRanged(0, 5), addGameObject, 1);

}

private function addGameObject(Timer:FlxTimer):Void 

{

var obj:GameObject = cast(this.recycle(GameObject), GameObject);

setStartingPosition(obj);

trace('created ' + obj.getType());

timer.start(FlxRandom.intRanged(2, 5), addGameObject, 1);

}

I populate the class: 

GameObjectsGroup extends FlxTypedGroup<GameObject>

With data of game objects of various subclasses of GameObject as shown in trace.

GameObjectsGroup.hx:157: building game objects for level 1
GameObjectsGroup.hx:78: adding: 0 to game objects pool
GameObjectsGroup.hx:78: adding: 1 to game objects pool
GameObjectsGroup.hx:78: adding: 2 to game objects pool
GameObjectsGroup.hx:78: adding: 3 to game objects pool
GameObjectsGroup.hx:78: adding: 4 to game objects pool
GameObjectsGroup.hx:78: adding: 5 to game objects pool
etc...

When I call recycle, it returns an empty object with no variables set. Why is this??
