Building table dynamically with PDFMake

Question

I'm working with pdfmake to generate pdf with javascript. I'm trying to build a table dynamically but not works ,this my attempt

$.ajax({
    type: "POST",
    url: myURL,
    success:function(data){
        /* data has a format like :
         *[{"peaje":"Peaje 1","ruta":"Ruta 1","fechaCruce":"2014-10-18","hora":"15:42","valor":"5000"},{"peaje":"Peaje 1","ruta":"Ruta 1","fechaCruce":"2014-10-18","hora":"14:21","valor":"7000"},{"peaje":"Peaje 1","ruta":"Ruta 1","fechaCruce":"2014-09-19","hora":"11:58","valor":"17000"}]
         */
        var peajes = JSON.parse( data );
        var body = [];
        var titulos = new Array( 'PEAJE', 'RUTA', 'FECHA CRUCE', 'HORA', 'VALOR' );
        body.push( titulos );
        for (key in peajes)
        {
            if (peajes.hasOwnProperty(key))
            {
                var peaje = peajes[key];
                var fila = new Array();
                fila.push( peaje.peaje.toString() );
                fila.push( peaje.ruta.toString()  );
                fila.push( peaje.fechaCruce.toString() );
                fila.push( peaje.hora.toString()  );
                fila.push( peaje.valor.toString() );
                body.push(fila);
            }
        }
        console.log( body );
        var docDefinition = {
            content: [
            {
                table: {
                   headerRows: 1,
                   widths: [ '*', 'auto', 100, '*' ],
                   body: body
                }
            }]
        };//end docDefinition
        pdfMake.createPdf(docDefinition).open();
    }//end success
  });

This is the example of the library http://pdfmake.org/#/gettingstarted

I don't know what am I doing wrong?

For multiple rows, here is an example

    var externalDataRetrievedFromServer = [
    { name: 'Bartek', age: 34 },
    { name: 'John', age: 27 },
    { name: 'Elizabeth', age: 30 },
];

function buildTableBody(data, columns) {
    var body = [];

    body.push(columns);

    data.forEach(function(row) {
        var dataRow = [];

        columns.forEach(function(column) {
            dataRow.push(row[column].toString());
        })

        body.push(dataRow);
    });

    return body;
}

function table(data, columns) {
    return {
        table: {
            headerRows: 1,
            body: buildTableBody(data, columns)
        }
    };
}

var dd = {
    content: [
        { text: 'Dynamic parts', style: 'header' },
        table(externalDataRetrievedFromServer, ['name', 'age'])
    ]
}
