Mahesh, If your object is already in JSON, there's really no need to use something like Json.NET. On the client, you could just parse out the JSON object using eval statements or jQuery's JSON functions, but that's not a good solution.
Something that popped out at me when I was rereading is that ASP.NET takes the JSON in a string prior to consuming it. What you're passing in is a JSON object. So, I'm wondering if ASP.NET isn't punting and producing an error in your IIS logfiles. Check this [1] website for more details.
