Dynamic MultiPage inside Repeater Item

[Ashraf Fayad]

Hi, I have created a TabStripe dynmically inside a Repeater item on repeater item databound event in the CodeBehind. It gets created well. But I'm not able to find it from Javascript using $find('TabStripClientId'). Although I write the clientID right, it returns null. 
I'm able to find it using $get() or document.getElementById() but then, it doesn't support the TabStrip client side events and it returns 'Object doesn't support this Property or Method'... Any solution? Thanks
