Show heads-up notification in cordova android

Anyone knows how to do heads-up notifications in cordova android?

I'm making an app where it is critical that a user sees a notification. I'm using the phonegap-build pushPlugin.

The server is a nodejs where i have tried:

var androidPayload = {
    data: {
        title: title,
        message: msg,
        notId:title,
        priority: 2
    }
};

or have i made something wrong?
