Accessing View function from internal functions in Ember

One of the views in my ember app has the following structure

export default Ember.View.extend({
    didInsertElement: function() {
        window.onload = function() {
            chrome.gcm.onMessage.addListener(function(message) {
                receiveGCM(message);
            });
        }
    },
    receiveGCM: function(message){
        console.log(message);
        //type check here
        //Then call necessary data insertion module
        //Or call the notification module
    }
});

This is throwing an error Error in event handler for gcm.onMessage: ReferenceError: receiveGCM is not defined

Calling receiveGCM(message) with the this object doesn't solve the problem. Wrong this object gets referred. I tried using bind(this). But that doesn't help.

How do I call receiveGCM() from the chrome listener method?
