node.js - nodejs email.send doesnt work inside function -

in code below email subject 'ok' sent not email 'not ok'? second 1 inside function.

var jsftp = require("jsftp"); var config = require('./config/config'); var email = require('./modules/mailer');  var ftp = new jsftp({     host: config.ftphost });  email.send(config.emailto, "emailtext", "ok");  ftp.list(config.ftpdir, function(err, res) {      console.log(config.emailto,res);      email.send(config.emailto, res, "not ok");      //process.exit(); }); 

it appears fetching , scraping log - - wrong approach. read on sendmail(1). packages postfix, exim, sendmail have protocols provide direct access server responses , can respond necessary.
