javascript - barba removeEventListener initiated in view

Question

I am new to barba.js and not a real JS Expert. So I have a simple question about Events inside a barba Container. I am initializing page specific Events in functions, which i Fire in barba afterEnter view.

barba.init({
         ...
         views: [ 
             {
                 namespace: 'frontend-development',
                 afterEnter(data) {
                     initTestBtn(data.next.container)
                 },
                }
             ]
        ...
 });

const initTestBtn = (next) => {
    const btn = next.querySelector('#testBtn')
    btn.addEventListener('click', (next) =>{
        alert('clicked');
    })
}

This works as expected. But I wonder if the old eventListener is really gone after leaving and returning on the page. Or did I cause a memory leak.

In other words: do I have to manually remove the eventListener? BTW do I use the right hook for initializing?

Thanks in advance, I hope one of you guys can enlighten me.
