Update ACF velden met AJAX via frontend

In functions.php

<form id="video_bekeken" action="">
        <input type="hidden" name="inschr" value="<?php echo get_the_ID(); ?>">
        <input type="submit" class="btn btn-primary" value="Naar stap 2">
        </form>
        <script type="text/javascript">
        var ajaxurl = "<?php echo admin_url('admin-ajax.php'); ?>"
        var form = "#video_bekeken";
          jQuery(form).submit(function(event) {
            event.preventDefault();
            jQuery.ajax({
              url: ajaxurl + "?action=video_bekeken",
              type: 'post',
              data: $(form).serialize(),
              success: function(data) {
                console.log("SUCCESS!");
                window.location.replace("https://www.iurislegal.nl/mijn-account/ondemand/#inschrijving<?php echo get_the_ID();?>");
              },
              error: function(data) {
                console.log("FAILURE");
              }
            });
          });
          </script>
