Data is not showing in category template

1. Added a Meta key, named ‘catsource’ by selecting ‘category’ as Meta taxonomy, it is showing in meta list.

2. Added following code in category.php to display this meta key data in category page:

<?php if (function_exists('get_terms_meta')) { ?>
    <?php $metaValue = get_terms_meta($category_id, $catsource); ?>
<?php } ?>

<?php echo $metaValue; ?>

But not showing at front-end in category page. Any clue?
