It is because your TextBox is inside a ContentPlaceHolder in the MasterPage. The ID gets modified when the page renders to something like ctl00_blah.

Try using a class selector instead like so:

$('textarea.jk').autoResize();

That should do the trick. In ASP.NET 4.0 you can force the ClientId to keep the name you specify, but I would just recommend using classes to make it easier. Another option would be to use ASP.NET to render the ClientId in the page like so:

$('textarea#<%=demo.ClientID %>').autoResize();
