Trying to show Google Maps using the Durandal. I'm now simply working with Durandal HTML Starter Kit so the other modules and all engine works properly. The thing is when I added the Google Map it doesn't fit the div size (the big part of div is just grey). As I understand, the problem is causing because Google Maps added before page is completely loaded. But I can't figure out how can I hook on page load event. Here is the module code:

define(['knockout', 'gmaps'], function (ko, gmaps) {

    return {
        displayName: 'Google Maps',
        myMap: ko.observable({
            lat: ko.observable(32),
            lng: ko.observable(10)}),

        activate: function () {
            console.log('activate');
            ko.bindingHandlers.map = {

                init: function (element, valueAccessor, allBindingsAccessor, viewModel) {
                    console.log('init');
                    var mapObj = ko.utils.unwrapObservable(valueAccessor());

                    var latLng = new gmaps.LatLng(
                        ko.utils.unwrapObservable(mapObj.lat),
                        ko.utils.unwrapObservable(mapObj.lng));

                    var mapOptions = { center: latLng,
                        zoom: 5,
                        mapTypeId: gmaps.MapTypeId.ROADMAP};

                    mapObj.googleMap = new gmaps.Map(element, mapOptions);
                }
            }
        },

        attached: function() {
            console.log('attached');

        },

        compositionComplete: function()
        {
            console.log('compositionComplete');


        }

    };


});

And a very simple HTML code:

<section>
    <div id="gmap-canvas" data-bind="map:myMap"></div>
</section>

I'm loading Google Maps with async plug-in in my shell.js. It works fine. Screenshot with trouble here - http://clip2net.com/s/ibswAa

P.S. div size is defined in .CSS file.

P.S. I tried to use getElementById approach provided here and it's work great if placed in compositionComplete block. But when I tried to move my bindings to this block nothing happens at all.

Thanks!
