Where can i put the callback?

[leekafai]

`var pluploader = new Pluploader({
uploadLimit: 16,
uploadDir: 'saved/'
});

pluploader.on('fileUploaded', function(file, req) {
console.log(file);
});

pluploader.on('error', function(error) {
throw error;
});

router.post('/upload', function(req, res){
pluploader.handleRequest(req, res)
});`
I've tried with res.send in the router.post function but it won't work.
I want to get the target path to return to client, what can i do?
