Thanks Jerome,
Hmmm.... That's a bummer.
In that case, trying to avoid a huge hassle, can you give me another tip?
Is there a constant section which I can hook into, which does not change when a variant is selected?
This way, the initialization will be made once when the page is loaded and even when a variant is selected, the code will work.
This way, I'll simply create a modal with all soundtracks for all variants together.
Not the most elegant solution, but I cannot invest so much now in re-writing the product page code only for that.
Thanks very much.
