runAction not excuted when invoked from CCNode (not onEnter )

runAction not excuted when invoked from CCNode (not onEnter )

I have Class that is CCNode extended from one of its methods i want to
excute actions but none of then are running : from this class :
class GameController : public CCNode
where i have also this:
void GameController::onEnter()
{
CCNode::onEnter();
}
this is the code i have :
bool GameController::removeFinalGems(CCArray* gemsToRemove)
{
onGemScaleInAnim = CCCallFuncND::create(this,
callfuncND_selector(GameController::OnGemScaleInAnim),gemsToRemove);
onRemoveGemScaleInAnim = CCCallFuncND::create(this,
callfuncND_selector(GameController::OnRemoveGemScaleInAnim),gemsToRemove);
CCSequence* selectedGemScaleInAndRemove =
CCSequence::create(onGemScaleInAnim,
onRemoveGemScaleInAnim,
NULL);
bool b = this->isRunning();
CCAction *action = this->runAction(selectedGemScaleInAndRemove);
return true;
}
void GameController::OnGemScaleInAnim(CCNode* sender,void* data)
{
CCArray *gemsToRemove = (CCArray*) data;
}
void GameController::OnRemoveGemScaleInAnim(CCNode* sender,void* data)
{
CCArray *gemsToRemove = (CCArray*) data;
}
it never gets to the OnRemoveGemScaleInAnim and OnGemScaleInAnim methods
