How to simulate a click on a google place autocomplete result?

Question

I'm struggling to interact with the results of my google autocomplete as part of my integration tests.

var placeSelector = '.pac-container .pac-item:first-child';

exports.runTest = function(test) {
    casper.waitForSelector('input.street-address'); // wait for page to load
    casper.sendKeys('input.street-address', 'fake address here', {keepFocus: true});

    casper.waitUntilVisible(placeSelector);

    casper.then(function() {
        casper.click(placeSelector); // THIS DOES NOT DO ANYTHING

        // if its possible to trigger the event in the context of the page, I 
        // could probably do so. However, I've scoured google docs and cannot find the 
        // event that is fired when a place is clicked upon.
        casper.evaluate(function() {
            //google.maps.places.Autocomplete.event.trigger(???);
        }); 
    });

    var formVal;
    casper.then(function() {
        formVal = casper.evaluate(function () {
            return $('input.street-address').val();
        });
    });
};

There is no result with the previous code, and the input is not filled, and hidden offers are not displayed.
