eglView->setViewName("TEST") is not working? Or what is wrong here?

cocos2d-x C++
#1

This code is not changing the title of the window

CCEGLView* eglView = CCEGLView::sharedOpenGLView();
eglView->setViewName("TEST");

Using this code and window title is changed:

HWND handle = eglView->getHWnd();
SetWindowText(handle, "MY_GAME_TITLE");

/EDIT
Tested on Windows 8 with cocos2d-2.1beta3-x-2.1.0.
