How to add touch event listener in Cocos2dx 3.1?

I used following code to add listener method to a Button in cocos2dx:

button->addTouchEventListener(this, toucheventselector(HomeScene::doSomething));

But since Cocos2dx 3.1 both toucheventselector and addTouchEventListener is depreciated. There is :

void addTouchEventListener(ccWidgetTouchCallback callback);

I can't make it work - I tried every macro I could find - callfuncO_selector, CC_CALLBACK etc. I just don't know how to point to my method that looks like this:

void HomeScene::doSomething(Ref *pSender, Widget::TouchEventType type);

Failed to find any clue from Google, forum, git, change log, tests...

You can also use this:

button->addTouchEventListener(CC_CALLBACK_2(HomeScene::doSomething,this));

to solve this issue :-)

You should use CC_CALLBACK_2 macro.

Well, I usually subclass my button and add listeners to it. Example: http://cocos2d-x.org/wiki/How_To_Subclass_Sprite_And_Add_Event_Listeners
