IActionFilter with culture

Hi,

I am studying filters issues. I want to set culture in filters. I got it. but I have to refresh page on filters why ?

If I dont use response.redirect, I cant see localization settings. if page changes, localization is ok. 

or I have to context.HttpContext.Response.Redirect(url)  

namespace MIS.WebUI.Filters
{
    public class CustomFilter : Attribute, IActionFilter
    {
        public void OnActionExecuting(ActionExecutingContext context)
        {
            ....
            CultureInfo ci = new CultureInfo("en-GB");
            Thread.CurrentThread.CurrentUICulture = ci;
            Thread.CurrentThread.CurrentCulture = ci;

            //string url = context.HttpContext.Request.Path;
            //context.HttpContext.Response.Redirect(url);
        }

        public void OnActionExecuted(ActionExecutedContext context)
        {
            
        }
    }
}
