Convert $.post to $.ajax

I want to convert my $.post call to $.ajax call because I need to clean the cache for every call.

My $.post call is as follows:

        $.post("test",   
            function(data) {
                $("#test").html(data);
                initTest();
            }
        ).success(function(){
            $('.box1').hide("slide", {direction: "left"}, 1000);
            $('.box3').show("slide", {direction: "right"}, 1000);
        });

I tried this but it doesn't work...

    $.ajax({
          type: "POST",
          url: "test",
          success: function (data) {
              $("#test").html(data);
              $('.box1').hide("slide", {direction: "left"}, 1000);
              $('.box3').show("slide", {direction: "right"}, 1000);
          },
          dataType: "json",
          cache: false
    });

$.ajax({
   method:"POST",
   url : "test.php",
   success : function(data) {
                $("#test").html(data);
                initTest();
                 $('.box1').hide("slide", {direction: "left"}, 1000);
     $('.box3').show("slide", {direction: "right"}, 1000);
            },
   cache : false
});

UPDATE I think you have problem in parsing data. In $.post by default is html dataType. In $.ajax call you changed it on "json". If no json is responsed so you have parse error and success handler dont call.
