Google reCAPTCHA for avia contact form

Ismael,

I tried this on the latest version of Enfold and it did not hide the send button (it was inactive) but no captcha is available to solve: https://kriesi.at/support/topic/starting-to-receive-spam-enquiries-from-contact-form-on-website/#post-817676

is this code still compatible with avia contact form?

function ava_custom_recaptcha(){
?>
<script type="text/javascript">
	var createCaptcha = function() {
		var button = jQuery(".avia_ajax_form .button");
		var parent = button.parent(".form_element");
		var captcha = jQuery("<p id='reCAPTCHAV2'></p>");

		button.attr("disabled", "disabled");
		captcha.insertBefore(parent);
	};

	createCaptcha();

	var onLoadCallback = function() {
		var publickey = 'YOUR PUBLIC API KEY';
		grecaptcha.render('reCAPTCHAV2', {
			'sitekey' : publickey,
			'callback' : 'onSuccessfullCallback'
		});
	};

	var onSuccessfullCallback = function() {
		jQuery("input[type=submit]").removeAttr('disabled');
	};
</script>
<?php
}
add_action('wp_footer', 'ava_custom_recaptcha');

if(!function_exists('avia_register_reCAPTCHAV2_scripts'))
{
	if(!is_admin()){
		add_action('wp_enqueue_scripts', 'avia_register_reCAPTCHAV2_scripts');
	}

	function avia_register_reCAPTCHAV2_scripts()
	{
		$prefix  = is_ssl() ? "https" : "http";
		$api_url = $prefix.'://www.google.com/recaptcha/api.js?onload=onloadCallback&render=explicit';

		wp_register_script( 'avia-google-reCAPTCHAV2-api', $api_url, array('jquery'), NULL, true);
		wp_enqueue_script(  'avia-google-reCAPTCHAV2-api' );
	}
}

function avf_recaCAPTCHAV2_defer_async($tag, $handle) {
    if ( 'avia-google-reCAPTCHAV2-api' !== $handle )
        return $tag;
    return str_replace( ' src', ' defer="defer" async="async" src', $tag );
}
add_filter('script_loader_tag', 'avf_recaCAPTCHAV2_defer_async', 10, 2);

Regards
