Cannot get content of template properly from plugin

[SiteTalkZone]

I use vB4.1

I'd like replace current block friend in MEMBERINFO template by another block with some changing about addition content.

I found the sidebar in MEMBERINFO template, like that:
<vb:comment>sidebar</vb:comment>
{vb:raw template_hook.profile_sidebar_first}
{vb:raw blocks.stats_mini}
{vb:raw template_hook.profile_sidebar_stats}

{vb:raw blocks.friends_mini}
{vb:raw template_hook.profile_sidebar_friends}

{vb:raw blocks.albums}
{vb:raw template_hook.profile_sidebar_albums}
{vb:raw blocks.groups}
{vb:raw template_hook.profile_sidebar_groups}
{vb:raw blocks.visitors}
{vb:raw template_hook.profile_sidebar_last}
<vb:comment>sidebar</vb:comment>


I write a new plugin by following code (hook location is member_build_blocks_start):
$templater = vB_Template::create('memberinfo_block_friends_mini ');
$friends_mini = $templater->render();

$miblock['block_template'] = $friends_mini;

$templater = vB_Template::create('profile_sidebar_friends');
$friends_hook = $templater->render();

$miblock['template_hook'] = $friends_hook;

vB_Template::preRegister('MEMBERINFO', array('newBlockFriends' => $miblock);


And then I replace above sidebar section with new code here:

<vb:comment>sidebar</vb:comment>
{vb:raw template_hook.profile_sidebar_first}
{vb:raw blocks.stats_mini}
{vb:raw template_hook.profile_sidebar_stats}

{vb:raw newBlockFriends.block_template}
{vb:raw newBlockFriends.template_hook}

{vb:raw blocks.albums}
{vb:raw template_hook.profile_sidebar_albums}
{vb:raw blocks.groups}
{vb:raw template_hook.profile_sidebar_groups}
{vb:raw blocks.visitors}
{vb:raw template_hook.profile_sidebar_last}
<vb:comment>sidebar</vb:comment>


But when I display my profile page, it only display Friend block with content is "has not made any friends yet" although I had made some friend before. It cannot display list of my friend in Friend block in sidebar of profile page.

Help me with this situation. It's urgent please.

Thanks!
