How to configure the correct sequence of execution of callbacks in the AMOCRM widget?

Question

CRM

Good afternoon, help with a problem.
I am making a widget for AMOCRM. The widget markup is loaded from a remote server. There is a problem, the initialization of the button is faster than the markup is loaded. As a result, when the button is pressed, nothing happens.
How can this problem be solved?

define(['jquery'], function($) {
    var CustomWidget = function() {
        var self = this, // для доступа к объекту из методов
            system = self.system, //Данный метод возвращает объект с переменными системы.
            langs = self.langs; //Объект локализации с данными из файла локализации (папки i18n)		

        this.getRenderData = function(w_code) {
            console.log('this.getRenderData');
            self.crm_post(
                'http://109.254.1.143/getCities', {
                    form_data: 'cities'
                },
                function(msg) {
                    console.log('msg ->>');
                    console.log(msg);
                    cities = msg
                },
                'json'
            );
            var render_data = '<link type="text/css" rel="stylesheet" href="/upl/' + w_code + '/widget/style.css"><div class="ac-form"><div id="js-ac-sub-subs-container"><form id="form"><div><input name="ordername" type="text" class="form-control" placeholder="Заголовок" required></div><div><textarea name="descr" class="form-control" placeholder="Опишите подробно что нужно сделать?" rows="4" required></textarea></div><div><select name="ordertype" class="form-control" required><option value="">Выберете тип работ</option><option value="1">Услуги электрика</option><option value="2">Электромонтажные работы</option></select></div><div><select name ="city" class ="form-control" required><option value="">В каком городе вы находитесь?</option>'
    
            for (i=0; i<cities.length; i++){
                render_data += '<option value="' + cities[i]["id"] + '">' + cities[i]["text"] + '</option>'
            }
