get_term_link() always links to homepage

Hi,

I created a custom post type with category taxonomy support.
On my archive template i have a dropdown with all categories to filter the archive.
Every category is linked with get_term_link(). The function works but it goes to the homepage. I want to link to the same page.

<?php
$args = array(
	'type'         => 'download',
	'child_of'     => 0,
	'parent'       => '',
	'orderby'      => 'name',
	'order'        => 'ASC',
	'hide_empty'   => 1,
	'hierarchical' => 1,
	'exclude'      => '',
	'include'      => '',
	'number'       => '',
	'taxonomy'     => 'category',
	'pad_counts'   => FALSE

);
$categories = get_categories( $args );
?>

<?php if ( count( $categories ) ) : ?>
<div class="btn-group margin-bottom-40">
	<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown" aria-expanded="false">
		Categorie
		<i class="fa fa-angle-down"></i>
	</button>
	<ul class="dropdown-menu" role="menu">
		<?php foreach ( $categories as $category ) : ?>
		<li <?php if ($category->cat_ID == get_query_var( 'cat' )) : ?>class="active"<?php endif; ?>><a href="<?php echo get_term_link( $category ); ?>"><?php echo $category->name ?></a></li>
		<?php endforeach; ?>
	</ul>
</div>
<?php endif; ?>

The links are now:
?cat=1
?cat=2
?cat=3

But it should be:
?page_id=5&cat=1
?page_id=5&cat=2
?page_id=5&cat=3

How can i fix this?
