Как передать элемент jQuery внутри функции — синтаксис

Мне нужно передать jQuery в качестве аргумента в первых двух функциях, иначе код внутри initialiseSticky не будет работать.
Это работает для document.ready, но не для ajaxComplete, мой синтаксис, вероятно, совсем не хорош...

jQuery(function($) { 
    console.log('document ready- sticky');
    initialiseSticky($);
});
$(document).ajaxComplete(function ($) {
    console.log('ajax complete- sticky');
    initialiseSticky($);

}(jQuery));

function initialiseSticky($) {
//my code
}

До того, как я отредактировал, функция со всем приведенным ниже кодом выглядела так:

!function ($) {
    //my code (now initialiseSticky function)
}(jQuery)

РЕДАКТИРОВАТЬ: я не знаю, поможет ли это, но вот веб-сайт, на котором эта проблема: http://lesdeuxvagues.com/demo посмотрите на меню, и оно закрепилось. Пока это работает при обычной загрузке страницы, но не с ajax.

РЕДАКТИРОВАТЬ 2: вот остальная часть кода:

function initialiseSticky($) {

    console.log('initialise- sticky');
