Push Notification not working

I’m implementing push notification, but don’t work.

Message log: TypeError: push.on is not a function.<<

in js:
var push = require(“FuseJS/Push”);

push.on(“registrationSucceeded”, function(regID) {
console.log("Reg Succeeded: " + regID);

in unoproj:
“Packages”: [

Where are error?

Are you using the latest version of Fuse? The on function is a relatively recent addition that came with our event system overhaul in version 0.30.

Thank you now, it worked.

I have another problem, I do not know how to get the regID on the already registered device
