<script type="text/x-handlebars" data-template-name="components/parent-category-row">
  <!-- ... -->
  <td class="topics">
    Topics: ({{this.category.totalTopicCount}})
  </td>

  <td class="replies">
    Replies: ({{this.category.totalReplyCount}})
  </td>

  <!-- ... -->
</script>

I believe something like this should work.
