Can't add 2 Cloud Functions?

Question

This is supposed to be an easy task. I'm so amazed by how much time I spent investigating the issue...

I have this Cloud Function in my index.js:

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);

exports.myFunction = functions.database.ref('/messaging/{pushId}')
.onWrite(event => {
    //do something      
});

According to this answer, I can simply add a second Function like so:

const functions = require('firebase-functions');
const admin = require('firebase-admin');
    admin.initializeApp(functions.config().firebase);

exports.myFunction= functions.database.ref('/messaging/{pushId}').onWrite(event => { //do something }); 

exports.secondFunction= functions.database.ref('/messaging/{pushId}').onWrite(event => {//do something });

But, in my Firebase Dashboard, there's still one Function listed: myFunction. Did I miss something? How can I add 2 Cloud Functions properly?
