Ajax not allowing $_POST submit

I am using Ajax to refresh two separte Divs at a ten second interval each:

 $(document).ready(function(){
        var timer, delay = 10000; // 10 seconds counted in milliseconds.
        var ID = $("td :submit").val();
        var info = {'userID': ID};
        timer = setInterval(function(){
            $.ajax({
                url: "inc/ans.php",
                type: "POST",
                data: info,
                success:function(data)
                {
                    $("div #ans").html(data);
                }
            });
        }, delay);
        var timer, delay = 10000; // 10 seconds counted in milliseconds.
        var ID = $("td :submit").val();
        var Pts = '';
        var info = {'userPts': Pts};
        timer = setInterval(function(){
            $.ajax({
                url: "inc/score_I.php",         
                type: "POST",
                data: info,
                    success:function(data){
                        $("div #scores").html(data);
                    }
                    });
        }, delay);
        });

But when I do this the information that the request pulls contains a <button> which when pressed adds to a database field.

 <button type="submit" name="pts" href="#" value="'.$id.'">+/button>

My question is does Ajax stop form submits from happening? Or am I missing something?
