The problem with your approach is that you are setting it where it is already too late for MVC to apply it. The following three lines of your code should be put in the method that shows the view (consequently the page) that you do not want to show.

Response.Cache.SetCacheability(HttpCacheability.NoCache);
Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1));
Response.Cache.SetNoStore();

If you want to apply the "no cache on browser back" behavior on all pages then you should put it in global.asax.

protected void Application_BeginRequest()
{
    Response.Cache.SetCacheability(HttpCacheability.NoCache);
    Response.Cache.SetExpires(DateTime.UtcNow.AddHours(-1));
    Response.Cache.SetNoStore();
}
