Function Pointer Fun

Code:

template<typename T>
class CUIButton : public CUIObject
{
public:
	CUIButton ()
	{
		CUITask::AddToList( this );
	}
	void Activate(int index=0)
	{
		// RUN whatever the button does
		if ( !Object || !Function )	// prevent calling a null
			return;

		if ( Animation.GetCurrentFrame() == 0 )
			Animation.SetCurrentFrame(1);
		else
			Animation.SetCurrentFrame(0);
		//(Object->*Function)();
	}
	void ChangeFunctionPointer( T * NewObject, void (T::*NewFunction)(void) )
	{
		Function = NewFunction;
	}
	void ( T::*Function )( void );
	T * Object;
}

See the Animation.Get / Set lines?

The (Object->*Function)() causes it to crash if I run those lines in it. This seems to be that Object isn't copying properly, which leads me to show you this:

Code:

class CTestTask : public ITask
{
public:

	AUTO_SIZE;

	bool Start();
	void Update();
	void Stop();
	void Test();

private:

	CSprite MySprite;
	CUIButton<CTestTask> MyButton;

};

Code:

bool CTestTask::Start()
{
	MyButton.ChangeFunctionPointer( this, Test );

	return true;
}

void CTestTask::Test()
{
	if ( MyButton.Animation.GetCurrentFrame() )
		MyButton.Animation.SetCurrentFrame(0);
	else
		MyButton.Animation.SetCurrentFrame(1);
}

Why does the function pointer crash it?

Edit:

Code:

void CTestTask::Test()
{
	if ( CUITask::Objects[0]->Animation.GetCurrentFrame() )
		CUITask::Objects[0]->Animation.SetCurrentFrame(0);
	else
		CUITask::Objects[0]->Animation.SetCurrentFrame(1);
}

If I do that, then it works. Problem? I'd have to also store the index. But I don't think I need that, do I?
