Anchor Link for custom Theme Icon

With this function I make my own Icon placed in the header:

// Register new icon as a theme icon
function avia_add_custom_icon($icons) {
	$icons['icon_name']	 = array( 'font' =>'fontello', 'icon' => 'ue881');
	return $icons;
}
add_filter('avf_default_icons','avia_add_custom_icon', 10, 1);
function avia_add_custom_social_icon($icons) {
	$icons['Icon Label'] = 'icon_name';
	return $icons;
}
add_filter('avf_social_icons_options','avia_add_custom_social_icon', 10, 1);

Now I want a anchor Link for this Icon with TARGET_SELF. Therefore I use this function:

//add_filter('wp_footer', 'avf_social_attr', 10);
function avf_social_attr() { ?>
<script>
(function($){
    $(window).load(function(){
		$(".social_bookmarks_icon_name a").attr("target", "_self");
	});	
})(jQuery);
</script>
<?php
}

But it is not working! Target of the link is always target=”_blank”
