How to get value inside phantomJS class?

Question

JavaScript

Good afternoon, I can not get the value inside .
Using phantomjs, I log in, after which I cannot get strong with the ".sms-packages__count" class.
With a delay, everything is OK, I rendered the page. It just returns null.
Thanks in advance!

var webpage = require('webpage');
var page = webpage.create();
page.settings = {
    loadImages: false,
    javascriptEnabled: true,
    encoding: "utf8",
    userAgent: 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36',
};

var page = require('webpage').create();
phantom.cookiesEnabled = true;
page.open("https://lk-ofd.taxcom.ru/#administration/features", function(status) {
    if (status === "success") {
    page.viewportSize = {
      width: 1920,
      height: 1080
    };
    page.evaluate(function() {
            document.getElementById("authorization-email-input").value = "aaaaaaaa";
            document.getElementById("authorization-password-input").value = "aaaaaaaa";
      
      document.getElementById("authorization-email-input").dispatchEvent(new Event('input', { bubbles: true }));
      document.getElementById("authorization-email-input").dispatchEvent(new Event('change', { bubbles: true }));
      document.getElementById("authorization-password-input").dispatchEvent(new Event('input', { bubbles: true }));
      document.getElementById("authorization-password-input").dispatchEvent(new Event('change', { bubbles: true }));
      window.setTimeout(function() {
        document.getElementById("authorization-submit-button").click();
      }, 1500);
        });
    window.setTimeout(function() {
      var elCount = page.content;
      var t = elCount.querySelector('.sms-packages__count').innerHTML;
      console.log(t);
      page.render('screenAuth.png');
      phantom.exit();
    }, 8000);
    }
});
