I was crazy with this Error (tabs w/ JSTool)

I have try many times and many ways to implement the "Tabs" using JsTools, but cannot success :( ,
by the way i have installed and enabled all JsTools Features, and I got the AJAX Feature inside it (very nice)

but when i try to create some tab page, my page cannot render the tabpage like in this site, http://stilbuero.de/jquery/tabs/
but it just render like common LIST and Header (UL -- LI and H2), like this below

* One
* Two
* Three

One
First tab content.
Two
Second tab content.
Three
Third tab content.
--------------------------------
i have tried to implement the simple tab page in my page.tpl.php page, like this script :

if (!$node) {
print my_tabs()
}

function my_tabs(){
$form = array();

$form['example1'] = array(
'#type' => 'tabset',
);
$form['example1']['tab1'] = array(
'#type' => 'tabpage',
'#title' => t('One'),
'#content' => t('First tab content.'),
);
$form['example1']['tab2'] = array(
'#type' => 'tabpage',
'#title' => t('Two'),
'#content' => t('Second tab content.'),
);
$form['example1']['tab3'] = array(
'#type' => 'tabpage',
'#title' => t('Three'),
'#content' => t('Third tab content.'),
);

return tabs_render($form);
}
---------------------------------------------------------
For the information, when i view the "view source" to my browser i cannot see the tabs.js inside it.., is it an issue ?
but i've tried to put it directly at the page.tpl.php file.., still cannot render :(

can anyone help me to resolve this problem... :(
