Event map is loaded missing: .on('tilesloaded' or 'idle' not working

I like to call a function when gmap3 is loaded successfully. But this way doesn't work:

`jQuery('#google-map5')
    .gmap3({ ... })
    .marker([ ...])
    .on(
        'tilesloaded',
        function() {
            console.log('map read');
        }
    )`

Is there any other way?
