How to prevent Idle Timeout in IIS Application Pool on a shared host – Plesk

I have my ASP.Net application uploaded on a shared host (godaddy plesk windows server). The Idle timeout on the shared host is set to 5 minutes and cannot be changed.

I have heard that the session timer can be reset by pinging the server before the timeout period has elapsed and I am trying to do this but my code doesn’t seem to work. I am using this as a guideline:

1. Keeping ASP.NET Session Open / Alive (The post by Maryan)
   and

2. https://gist.github.com/KyleMit/aa4f576fa32bf36fbedab5540c18211d

Basically in my Home controller I have put this code:

 [HttpPost]
 public JsonResult KeepSessionAlive()
 {
     return new JsonResult {Data = "Success"};
 }

In my Scripts folder I have put this script titled SessionUpdater.js

 SessionUpdater = (function () {
var clientMovedSinceLastTimeout = true; //I want it to be always on so if statement fires
var keepSessionAliveUrl = null;
var timeout = 1 * 1000 * 60; // 1 minutes

function setupSessionUpdater(actionUrl) {
    // store local value
    keepSessionAliveUrl = actionUrl;
    // setup handlers
    listenForChanges();
    // start timeout - it'll run after n minutes
    checkToKeepSessionAlive();
}

function listenForChanges() {
    $("body").one("mousemove keydown", function () {
        clientMovedSinceLastTimeout = true;
    });
}
// fires every n minutes - if there's been movement ping server and restart timer
function checkToKeepSessionAlive() {
    setTimeout(function () { keepSessionAlive(); }, timeout);
}

function keepSessionAlive() {
    // if we've had any movement since last run, ping the server
    if (clientMovedSinceLastTimeout == true) {
        $.ajax({
            type: "POST",
            url: keepSessionAliveUrl,
            success: function (data) {
                // reset movement flag
                clientMovedSinceLastTimeout = true; //always on
                // start listening for changes again
                listenForChanges();
                // restart timeout to check again in n minutes
                checkToKeepSessionAlive();


            },
            error: function (data) {
                console.log("Error posting to " & keepSessionAliveUrl);
            }
        });
    }
}

// export setup method
return {
    Setup: setupSessionUpdater
};
 })();

And then in both my layout page and in my homeindex page (in case partial view doesnt work for some reason) I put this reference:

 <script type="text/javascript">
// initialize Session Updater on page
SetupSessionUpdater('/Home/KeepSessionAlive');
SessionUpdater.Setup('@Url.Action("KeepSessionAlive","Home")');
 </script>

My Problem is that despite doing this the session still logs me out every 5 minutes of being idle and I can tell that the app pool recycles because the website takes forever to fire up again. What am I doing wrong? How can I get this to stop logging me out.

Any information or being pointed in the right direction is appreciated.
