ASP.Net MVC: Call Controller Action in JavaScript Timer based on condition using jQuery AJAX

Hi Team,

I had a requirement like, need to validate OTP.

In that screen we need to bring timer. for that i had given below script and it is working fine too.

But once label reaches 0.00 it should trigger to contoller action.

Kindly let me know the possiblity.

<script>
    var timer2 = "1:01";
    var interval = setInterval(function () {
        var timer = timer2.split(':');
        //by parsing integer, I avoid all extra string processing
        var minutes = parseInt(timer[0], 10);
        var seconds = parseInt(timer[1], 10);
        --seconds;
        minutes = (seconds < 0) ? --minutes : minutes;
        if (minutes < 0) clearInterval(interval);
        seconds = (seconds < 0) ? 59 : seconds;
        seconds = (seconds < 10) ? '0' + seconds : seconds;
        //minutes = (minutes < 10) ? minutes : minutes;
        $('.countdown').html(minutes + ':' + seconds);
        timer2 = minutes + ':' + seconds;
    }, 1000);
</script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="form-group">
    OTP is valid till: <label id="lblcountdown" class="countdown"></label> @*<div id="divCountdown" class="countdown"></div>*@
</div>

Thanks in advance.
