problem in fragmnet caching

Hi :)
I have written following code for Fragment caching,but it isnot working..

I have added below code in ASCX html section and added this in aspx file.

<@OutPutCache Duration="60" VaryByparam="none">

and written this code in Page_Load event so that after specified duration it will displayed a current date and time

Response.Write(DateTime.Now.ToString());

can anybody tell me what attribute is missing..

thanks in advance
