White notification icon won't turn into black on white status bar

Question

I am using white notification icon. When status bar is white, all apps notification icons turn into black but my apps icon stays white, so becomes invisible. How can I make status bar icon color adaptive? It must be black or white according to light or dark status bar.

It should just turn into light(white) or dark(black) but it won't.
