Fetch and Display RSS Feeds using C# in ASP.Net MVC

Hi anyone knows how to add a button and an on-click method that will do some C# code on an MVC Index View ? 

If I simply drop the control, say just a simple button over the View Index then double click on it, it automatically creates the following piece of code in the Markup Index view, which allows me to use C# code which is great !!  problem is that it doesn't work !! 

<script runat="server">

    protected void Button1_Click1(object sender, EventArgs e)
    {
        TextBox1.Text = "myTest";
    }
</script>
