                <a href='#'><span>Profile</span></a>
                <ul>
                    <form method="post" >
                    <table>

To update data in the database please change to below code.

if (Save != null)
{

    using (var context = new SYTEntities())
    {
        var s = context.tblUsers.Where(a => a.UserID == id).FirstOrDefault();
        s.FirstName = FirstName;
        s.LastName = profile.LastName;
        s.EmailID = profile.EmailID;
        s.MobileNumber = profile.MobileNumber;

        context.SaveChanges();

    }

}

remove context.tblUsers.Add(s); from your code

using (var context = new SYTEntities())
{
    var s = context.tblUsers.Where(a => a.UserID ==     id).FirstOrDefault();
    s.FirstName = FirstName;
    s.LastName = profile.LastName;
    s.EmailID = profile.EmailID;
    s.MobileNumber = profile.MobileNumber;

    // SET STATE TO CHANGED
    db.Entry(tblUsers).State = EntityState.Modified;

    context.SaveChanges();

}
