I use the same mixture as you. If you ever need to test a bottle, fill a pot with warm water (~95 degrees) and let the bottle float in it (without tipping over) for a few minutes. Yeast metabolism goes absolutely gangbuster with a slight increase in temperature (that's why we use it make bread rise quickly in an oven). If you still don't see any bubbles after a good 20 minutes, the mix is used up or the bottle is leaking. I can get lots of bubbles using this method even when I freshly mix a batch and test it less than an hour later.
