javascript - Node/Express not saving updated company information to DB -

i'm new node/express, , trying implement block updates company's information. have number of console.log statements tracking variables throughout block, , seems working fine until last saving line. doing wrong?

// edit company metric information   editmetrics: function(link, form, cb) {     companies.findone({ permalink: link }, function (err, company) {       if (err)  return done(err);        // iterate through form fields       for(var field in form) {         console.log(field);  // looks great          if(typeof(company.operational[field]) !== 'undefined') {           company.operational[field].unshift({             timestamp: new date(),             value: form[field]           });         }          if(typeof(company.user_metrics[field]) !== 'undefined') {           company.user_metrics[field].unshift({             timestamp: new date(),             value: form[field]           });         }          if(typeof(company.economics[field]) !== 'undefined') {           company.economics[field].unshift({             timestamp: new date(),             value: form[field]           });          }             }        console.log(company); // looks great        // save & redirect updated profile       company.save(cb());  // reason isn't saving     });   }, 

callback:

companymodel.editmetrics(link, req.body, cb = function(error, result) {      res.redirect('/portfolio/' + link);    }); 

the problem last line:

company.save(cb());

should be:

company.save(cb);

basically executing callback , passing result save function, when need passing function pointer save function.

also make sure callback signature matches node convention of function(error, result) result value expecting.
