Request.IsAuthenticated not working in IE repeated partial view MVC3 - asp.net-mvc-3

Question

I have strange problem with an MVC3 application. The application works as expected on Firefox and Chrome but not IE.
I have a partial view that is repeated in a loop on a page. At the bottom of the partial view I am doing a check on Request.IsAuthenticated. If authenticated an ajax form should display. This works on all browsers but IE. In IE if there is more than one instance of the partial view rendered the form does not appear (even when the user is logged in).
I have attached the partial view code below. The form is right at the bottom.
Has anyone else had a similar problem? Any help or thoughts would be great. Thank you

I would double check that rendered markup is valid. It's possible that one of your IDs is duplicated and that IE is just kicking it away.
UPDATE: You have 4 elements with ID t.titleId. As I said above, you can have only one specific ID on the HTML page. Move this to class instead and all should be fine.
