JS is loaded, still doesn't work

I can see that the javascript file is being loaded. However, the page still refreshes when a variable product is added to the cart. Button does have the proper classes. Unfortunately, I can’t provide a link as i’m currently developing locally. Any idea what I might be missing?

Thanks!
