jqxDropdownlist custom rendering issue Posts

Actually I’m using a jqxDropDownList widgets, loading data from a service written in php that send back JSON data.

these are the json data returned back by Produzione_materiali/get_elenco_materiali service:
[{"TotalRows":"6","Rows":[{"codmateriale":"ALLUMINIO","unita":"PZ","prezzo":"0.00000"},{"codmateriale":"FERRO","unita":"PZ","prezzo":"0.00000"},{"codmateriale":"LEGNO","unita":"PZ","prezzo":"0.00000"},{"codmateriale":"OTTONE","unita":"PZ","prezzo":"0.00000"},{"codmateriale":"PLASTICA","unita":"PZ","prezzo":"0.00000"},{"codmateriale":"ZAMA","unita":"KG","prezzo":"2.25000"}]}]

This is the javascript code to display jqwidget:

        var source =
        {
            datatype: "json",
            datafields: [
                { name: 'codmateriale' },
                { name: 'unita' }
            ],
            url: '<?php echo site_url("/Produzione_materiali/get_elenco_materiali/");?>',
            root: 'Rows',
            async: false
        };
        var dataAdapter = new $.jqx.dataAdapter(source);

        $("#materiale").jqxDropDownList({
            source: dataAdapter, displayMember: "codmateriale", valueMember: "codmateriale", width: '100%', height: 25
        });

What I would need, is to show in the dropdown something like “codmateriale” + “[” + unita + “]”
I would like to use custom rendering but I was not able to figure out how to get the 2 fields:

            renderer: function (index, label, value) {
                var datarecord = source[index];
                var text = source.codmateriale + "[" + source.unita + "]"
                return text;
            }

Could someone help me?

Matt
