script.js

$(document).ready(function ($) {
        $(document).on('click', '.checkbox', function(){
                $(this).parent().addClass('completed');
                $(this).attr('disabled', true);

                uid = $(this).attr('data-uid');
                $.get("/api/complete/" + uid);
        });

        $(document).on('click', '.remove', function(){
                $(this).parent().remove();
        });
});

В консоли указывает на эту стр $.get("/api/complete/" + uid);
