I think the part that activates the menu needs to be inside a tag that has the id being registered. Here part of the default postbit template:

<div id="postmenu_$post[postid]">
	<if condition="$show['profile']">
	    <a class="bigusername" href="member.php?$session[sessionurl]u=$post[userid]">$post[musername]</a>
	    $post[onlinestatus]
	    <script type="text/javascript"> vbmenu_register("postmenu_$post[postid]", true); </script>
	<else />
	    $post[musername]
	</if>
</div>

It looks like you took out the <div id="postmenu_$post[postid]"> part.
