Make your own component

$(function () {

/**
 *
 * Kontrol core
 *
 */


// Component logic
k.NewComponent = function () {

    // extends Kontrol Object
    k.o.call(this);

    /**
     *
     * your code
     *
     */
};

// jQuery plugin
$.fn.newcomponent = function (o) {
    return this.each(
        function () {
            var k = new k.NewComponent();
            k.o = o;
            k.$ = $(this);
            k.run();
        }
    ).parent();
};

});
