bulma-steps next button doesnt step

Hi!

I have a problem that many guys on the internet have, but no answer helped me so far. I'm making a project in VueJS and wanted to implement bulma-steps. I had troubles there and first thought, that there is a problem when loading the JS file to by component. That's why I, for the test purposes, tried to seperate code into some test ordinary .html files to see if it works there. I imported the css, js... and JS part still doesn't happen to work. It just references to the '#' and that's it. See the code in the attachment. (the bulma-steps.min.css works, so don't worry about that css reference)
