pager disappeared when i using views_embed_view in parent views's field tpl file

I create a view, and try to override one field using views_embed_view.
Here is my code in views-view-field--nid-1.tpl.php:
print views_embed_view('total_members_number','default',$output);

I get the correct result.But when i add more test datas, I find that the pager disappear.

When i change the code of views-view-field--nid-1.tpl.php to:
print $output;

The pager appear.

It seems that i could not use views_embed_view in another view's tpl file.
