javascript if statement does not work with razor

i have failed to validate if statement as shown in code below ,while i can get the value of "@Model.FreelancerProposals.Where(a => a.IsAssigned == true)"in html but cant validate if statement using the same value in javascript, what is your advice for this scenario.

<script>
        if(@Model.FreelancerProposals.Where(a => a.IsAssigned == true).Count() > 0)
        {
            function addDays(date, days) {
                var result = new Date(date);
                result.setDate(result.getDate() + days);
                return result;
            }
            // Set the date we're counting down to
            /**/
            var countDownDate = new Date("@Model.FreelancerProposal.DateofRecord.Month, @Model.FreelancerProposal.DateofRecord.Day, @Model.FreelancerProposal.DateofRecord.Year @Model.FreelancerProposal.DateofRecord.Hour:@Model.FreelancerProposal.DateofRecord.Minute:@Model.FreelancerProposal.DateofRecord.Second").getTime();
            countDownDate=addDays(countDownDate,@Model.FreelancerProposal.DaysRequired)    /**/
            // Update the count down every 1 second
            var x = setInterval(function () {

            // Get today's date and time
            var now = new Date().getTime();

            // Find the distance between now and the count down date
            var distance = countDownDate - now;

            // Time calculations for days, hours, minutes and seconds
            var days = Math.floor(distance / (1000 * 60 * 60 * 24));
            var hours = Math.floor((distance % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
            var minutes = Math.floor((distance % (1000 * 60 * 60)) / (1000 * 60));
            var seconds = Math.floor((distance % (1000 * 60)) / 1000);

            // Display the result in the element with id="demo"
            document.getElementById("demo").innerHTML = days + "يوم " + hours + "س "
                + minutes + "د " + seconds + "ث ";

            // If the count down is finished, write some text
            if (distance < 0) {
                clearInterval(x);
                document.getElementById("demo").innerHTML = "إنتهى الوقت المدد";
            }
            }, 1000);
        }
    </script>
