Why does ReCaptcha disappear on an ajax request in a Bitrix form?

Question

JavaScript

Good evening. I have a form component. I call like this:

<?$APPLICATION->IncludeComponent(
  "vilka:feedback", 
  "style2", 
  array(
    "USE_CAPTCHA" => "Y",
    "OK_TEXT" => GetMessage("OK_TEXT"),
    "EMAIL_TO" => $defEmail,
    "SHOW_FIELDS" => array(
      0 => "NAME",
      1 => "PHONE",
    ),
    "REQUIRED_FIELDS" => array(
      0 => "NAME",
      1 => "PHONE",
    ),
    "AJAX_MODE" => "Y",
    "AJAX_OPTION_JUMP" => "N",
    "AJAX_OPTION_STYLE" => "Y",
    "AJAX_OPTION_HISTORY" => "N",
    "AJAX_OPTION_ADDITIONAL" => "",
    "FORM_ID" => "548f0a3cd5265",
    "MAIL_TITLE" => GetMessage("MAIL_TITLE"),
    "COMPONENT_TEMPLATE" => "style2"
  ),
  false
);?>

On the site saratovutil64.ru you can see the recaptcha in the form "LEAVE YOUR REQUEST". Calling the captcha with the following code:

<div class="g-recaptcha" data-sitekey="<?=RE_SITE_KEY?>"></div>

where RE_SITE_KEY is the site key.
The Google script is included in the header of the site.
Help me please.

Answer 1

well, you can see that the controller returns html in the response, which does not contain a captcha:
Accordingly, look for this template that arrives in the response and insert the captcha there

Answer 2

Just add api.js connection not in header.php. And right in the component template above the block

<div class="g-recaptcha" data-sitekey="<?=RE_SITE_KEY?>"></div>
