        data: {

        },
        dataType: 'json',
    success: function(data){

            console.log(data); // this equals the id of the row in the db, 
                               // and it's what I want to make into the value of 
                               // the option that's been added.

            // I've tried many more than the following and none have worked.

            // $(this).attr("value", data);
            // $(this).val(data).change();
            // $(this).select2("val", data);
            // $('.my-select2').select2('data', {id: data, text: 'original value'});
        }       
    });
