        data:   $.getJSON("/InspekcijskeKontrole/Check?id1=" + $("#kombo3").val() + "&id2=" + $("#kombo4").val(), function (data) {

            if (data.InspekcijskoTijeloId != -1 && data.ProizvodId != -1) {
                $.getJSON("/Proizvodi/VratiIme/" + data.ProizvodId, function (ime) {

                    if (ime != null) {
                        $("#modalni1 p").text("Inspekcijska kontrola za " + ime + " je vec izvrsena");
                        $("#modalni1").modal({ backdrop: "static" });

                    }
                });

            } 

        }),
        data:form.serialize(),

        success: function (response) {

         alert("Informacije su uspjesno ubacene");
         window.location.href = "/InspekcijskeKontrole/Index";


        },
        error: function (greska) {
            alert("Doslo je do greske pri ubacivanju");
        }

    });

});code here

This doesn't work because the two inner "Check" and "VratiMe" ajax calls finish after the post has already completed.

Because they are Asynchronous (ie queue up and return immediately and then complete at a later date).

You should be able to change the order of your calls to something like:

var form = $(this).closest("#forma1");

$.getJSON("/InspekcijskeKontrole/Check?id1=" + $("#kombo3").val() + "&id2=" + $("#kombo4").val(), function (data) {

    if (data.InspekcijskoTijeloId != -1 && data.ProizvodId != -1) {
        $.getJSON("/Proizvodi/VratiIme/" + data.ProizvodId, function (ime) {

            if (ime != null) {
                $("#modalni1 p").text("Inspekcijska kontrola za " + ime + " je vec izvrsena");
                $("#modalni1").modal({ backdrop: "static" });
            }
        });
    }
    else {

        $.ajax({
            type: "POST",
            url: form.attr("Create"),

            data:form.serialize(),

            success: function (response) {

             alert("Informacije su uspjesno ubacene");
             window.location.href = "/InspekcijskeKontrole/Index";


            },
            error: function (greska) {
                alert("Doslo je do greske pri ubacivanju");
            }

        });
    } 
});
