1.                     converters: {
                           "text json": function(data) {
                               return data;
                           }
                       }

without this, one application from one tutorial does not work... here's the rest of the code:

1.             $("#buttonDiv").click(function(e) {
                   var unetiPodaci = $("#orderForm").serialize();
                   e.preventDefault();
                   $.ajax({
                       url: "http://localhost",
                       type: "post",
                       data: unetiPodaci,
                       dataType: "json",
                       dataFilter: function(siroviOdgovor, dataType) {
                           var jsonOdgovor = $.parseJSON(siroviOdgovor);
                           var cleanData = {
                               totalItems: jsonOdgovor.totalItems,
                               totalPrice: jsonOdgovor.totalPrice
                           };
                           delete jsonOdgovor.totalItems;
                           delete jsonOdgovor.totalPrice;
                           cleanData.products = [];
                           for (prop in jsonOdgovor) {
                               cleanData.products.push({
                                   name: prop,
                                   quantity: jsonOdgovor[prop]
                               })
                           }
                           return cleanData;
                       },
                       converters: {
                           "text json": function(data) {
                               return data;
                           }
                       },
                       success: function(data) {
                           obradiPrimljeniOdgovor(data);
                       }
                   })
               })

Correct me if I'm wrong , maybe it means that the response (which is a text) will be converted to json? If so, then why is something like that needed when we have:

1. dataType: "json",
   dataFilter: function(siroviOdgovor, dataType) {
         var jsonOdgovor = $.parseJSON(siroviOdgovor);

where it is already stated that we expect "json" and in dataFilter we parsed response to JSON?
