jQuery Waypoints change navbar styling on scroll

I have the following navbar code with BS4

    <div id="navbar">
        <nav class="navbar fixed-top navbar-expand-lg navbar-dark bg-inverse hidden-sm-down bg-custom">
          <div class="container-fluid">
            <a class="navbar-brand" href="#">
              <p class="icon-sblack icon-brand text-white my-0">
            </a>
            <ul class="navbar-nav navbar-collapse justify-content-end mx-3">
              <li class="nav-item">
                <a class="nav-link" href="#top">Home</a>
              </li>
              <li class="nav-item">
                <a class="nav-link" href="#about">About</a>
              </li>
              <li class="nav-item">
                <a class="nav-link" href="#">Portfoio</a>
              </li>
              <li class="nav-item">
                <a class="nav-link" href="#">Contact</a>
              </li>
            </ul>
          </div>
        </nav>
      </div>

    <div id="changenav" style="margin-top: 50px; height: 500px; width: 100%; background-color: black;"></div

I'd like it so the navbar doesn't show until the visitor scrolls down, then I'd like the navbar to become black on white after they scroll past an element with the name #scrollPast instead of white on black. How can I do this? I am already sourcing jQuery.

    var waypoint = new Waypoint({
      element: document.getElementById('changenav'),
      handler: function(direction) {
          $(".navbar").removeClass("bg-inverse");
          $(".navbar").removeClass("navbar-dark");
          $(".navbar").removeClass("bg-custom");
          $(".navbar").addClass("navbar-light");
          $(".navbar").addClass("scrolled-nav");
        } else {
          $(".navbar").addClass("bg-inverse");
          $(".navbar").addClass("navbar-dark");
          $(".navbar").addClass("bg-custom");
          $(".navbar").removeClass("navbar-light");
        }
      }
    })

I am using the jQuery waypoints plugin.
