[jQuery] .ajaxSend fires six times

[jQuery] .ajaxSend fires six times


Hello!
I need a callback to be executed, when any ajax request begins. I used
this code:
var cnt=0;
$('*').ajaxSend(function() {
    cnt++;
});
function Teszt() {
    $.post('jquerytest.php');
    alert(cnt);
}
When i call function Teszt(), the alert shows '6'. Why?
