Sending a integer value to php with javascript and returning values

I have this div area in my index and I want to use it as a button (for graphical issues) and when this button is cliked I want it to send this value to php file and I want to return some values according to this value. Here is what I've done this far but it didn't work at all.

this is my output.php (index)

<script src="http://ift.tt/1APuVEV"></script>
<script type="text/javascript"> 
        int sayac = 1;
        $(document).delegate("#klikme", "click", function() {
                $.post('sayac.php',{"komut": sayac }, function(data){
                        $('#output').html(data);
                });
                sayac = sayac + 1;
        });

</script>
<div id = "klikme">
        KLİK ME!
</div>

<div id = "output">
<?php include 'sayac.php'?>

</div>

sayac.php

<?php 
        if(isset($_POST["komut"]))
        {
                switch($_POST["komut"])
                {
                        case "1":
                                echo "This is one";
                                break;
                        case "2":
                                echo "This is two";
                        default:
                                echo "Something is wrong";
                                break;
                }
        }
        return false;
?>
