:?: Want to show jsrollPane in qtip --onRender function

:?: Want to show jsrollPane in qtip --onRender function

hi,there.

I use Jscrollpane for my new project. which is great and works on the page.

The page works fine but when it is called inside the qtip, the customized
bar disappear.

see the custmized scroll barhttp://81.171.199.24/qtip/scrollpanel.html
See qtip example (click snowy Owl link): http://81.171.199.24/qtip/index.html

The developer from qtip suggest I should include the scroll script on your
qTip page, and call the jScrollPanel method within the onRender callback of
your tooltip otherwise won't work since it's simply retrieving the HTML
from the page, not parsing the JS on it too.

So I tried to put the code in the onRender function like

onRender: function(){

$U('#pop-panel').jScrollPane({scrollbarWidth:15,
scrollbarMargin:0});

}

But I can't get any luck.

Please give some suggestions, thank you so much for the help.
