href generated in javascript doesnt hit mvc action in second time

Question

I generate html like this in javascript as you can see theres an a tag in html

when I click first time in link it hit the action, but sometimes (can say 90% of cases) second click doesnt hit the action unless I clear the firefox or chrome cache what's going here? and how can I solve this problem?

$.each(response, function (index, item) {
                            htmlcontent = "<div class=''>" +
                                "<a target='_blank' href='/Stat/" + item.Code + "/" + item.RId + "'>" +
                                "<img class=''  src='/Images/" + item.ImageId + "'/>" +
                                "</a>" +
                                "</div>";
                            $('.div_SecondCol').eq(index).html(htmlcontent);
                        });

and this is action

 // GET: Stat/{code}/{RId}
public ActionResult AdsStat(string Code, int? RId)
        {

            try
            {
                #region Load Data
                  //some code
                #endregion
                #region Insert Data
                  //some code
                #endregion

                return RedirectPermanent(externalUrl);

            }
            catch (Exception e)
            {

            }
        }

when I add a random number at the end of href it works! but I need to know what's going here?

var randnum = Math.floor((Math.random() * 1000) + 1);
"<a target='_blank' href='/Stat/" + item.Code + "/" + item.RId + "?rnum=" + randnum + "'>" +

Do you get any errors in console on second click? And are sure that Item is not null after redirect from first click? — Kamil Folwarczny, Sep 24 '18 at 06:40
no there's no error, and in second click it goes to external href without hitting the action — lili farabari, Sep 24 '18 at 06:41

I think its because HTTP Permanent Redirects 301 is cached by default. So browser opens cached page with identical URL, instead of making trip on server. Thats why its working, when you add random url parameter.
