Newely added social icon not showing up

Hi,

I added the code bellow to my functions.php to add a google icon on my social settings. The icon is not showing in the header. The rollover is present but no icon.

<?php

/*
* Add your own functions here. You can also copy some of the theme functions into this file. 
* WordPress will use those functions instead of the original functions then.
*/
// Register new icon as a theme icon
function avia_add_custom_icon($icons) {
	$icons['google']	 = array( 'font' =>'fontello', 'icon' => 'uf1a0');
	return $icons;
}
add_filter('avf_default_icons','avia_add_custom_icon', 10, 1);

// Add new icon as an option for social icons
function avia_add_custom_social_icon($icons) {
	$icons['google'] = 'google';
	return $icons;
}
add_filter('avf_social_icons_options','avia_add_custom_social_icon', 10, 1);

I also added this css

/* google Icon Style*/
#top #wrap_all .av-social-link-google:hover a {
    background-color: #4688F1 !important;
    color: white !important;
}
