Answer 1

try this for select2 latest version

processResults: function (data, params) {

               var results = [];

                if (data != null && data.length > 0) {

                    $.each(data, function (index, item) {

                        results.push({
                            id: item.id,
                            text: item.text
                        });
                    });
                }
                return {
                    results: results
                };
};

for select2 3.5.2 version:

results: function (data, page) { // parse the results into the format expected by Select2.
                var results = [];

                if (data != null && data.length > 0) {

                    $.each(data, function (index, item) {

                        results.push({
                            id: item.id,
                            text: item.text
                        });
                    });
                }
                return {
                    results: results
                };
            },
            cache: true
        }
