Jquery $.each sync

Question

I have a GRID on a screen where, each line has a button that calls a javascript method passing some values. In this method, a call is made via getJSON.

The problem is that even in this call, specifying async: false, the $.each does not wait to rotate the next line.

Follows the code of $.each:

console.log('start');
$('#btn_sugerir_todos').click(function(){

    $('.btnSugerir').each(function(index, value) {
        var def = new $.Deferred();
        var id        = $('#' + value.id).attr('data-id');
        var ordcol_id = $('#' + value.id).attr('data-ordcol_id');
        var data      = $('#' + value.id).attr('data-data');
        var hora      = $('#' + value.id).attr('data-hora');
        var cubagem   = $('#' + value.id).attr('data-cubagem');
        var fatexp_id = $('#' + value.id).attr('data-fatexp_id');
        console.log(id);

        sugerirVeiculo(jQPlanejador, id, ordcol_id, data, hora, cubagem, fatexp_id, false);
    });
    console.log('Fim');
});

All the console.log() are instantaneous in processing, but the actual result of the function sugerirVeiculo() is not.

Someone knows how forced to wait for the result line by line?
