Autoplay on scroll

Hi,
I would like the autoplay to be activated when scrolling down to the carousel, and not on loading the page.

I have customize javascript on my child-theme, but doesn’t work. I’ve noticed ‘false’ instruction works but ‘true’ doesn’t. Nor if I take it out of the waypoint function.

Any idea would be appreciated.
Thanks in advance.

jQuery(".wcp-slick").data('autoplay',false);

var waypoint = new Waypoint({
    element: document.getElementsByClassName('wcp-slick'),
    handler: function(direction) {
       jQuery(".wcp-slick").data('autoplay',true);
       console.log("Waypoint");
    }
})
