Multiple checkboxes with Ajax strange behavior

I have a form with many checkboxes, and a PHP page is called for updating the database on each click.

HTML

<form>
   <input type="checkbox" name="status1" id="event_status1" value="1" >
   <input type="checkbox" name="status2" id="event_status2" value="1" >
   <input type="checkbox" name="status3" id="event_status3" value="1" >
</form>

JQuery

  $('input:checkbox').change(function(e) {
     e.preventDefault();
     var isChecked = $("input:checkbox").is(":checked") ? 1:0; 
     $.ajax({
           type: 'POST',
           url: "admin-ajax.php",
           data: { event_status:$("input:checkbox").attr("id"), status:isChecked},
           success: function (response) {
              console.log(response);
           }
     });        
  });

It works well when I check/uncheck each checkbox individualy.

If I check the 3 boxes, the last I have checked won't send "0" status if I uncheck it but wil always send "1".
