Bing Maps tryPixelToLocation on Polygon

I'm trying to create a concave polygon by getting user clicks on a map. I can create convex polygons just fine. But when I attempt to create the concave polygon I have to click on the polygon itself giving me the following error:

e.target.tryPixelToLocation is not a function

Allow me to elaborate further. The user clicks on the map and a pin is placed on the map to show where they just clicked. They click two more time and they now have a triangle drawn on the map. When they attempt to click inside that triangle to draw the fourth point, creating a concave polygon, they get the above error.

The code I am using is below 

function GetMap(sender, args) {
    map = new Microsoft.Maps.Map(document.getElementById("mapDiv"), {
        credentials: "XXXXX",
        enableSearchLogo: false,
        enableClickableLogo: false,
        disableBirdseye: true
    });
    map.setView({
        zoom: 17,
        center: new Microsoft.Maps.Location($('#startLatitude').val(), $('#startLongitude').val()),
        mapTypeId: Microsoft.Maps.MapTypeId.aerial,
        labelOverlay: Microsoft.Maps.LabelOverlay.visible
    });
    Microsoft.Maps.Events.addHandler(map, 'click', getUserClick);
}

function getUserClick(e) {
    alert(e.targetType); // <--- When this is 'Polygon' we get the error 
    if (e.mouseMoved === false && e.isPrimary === true) {
        var p = new Microsoft.Maps.Point(e.getX(), e.getY());
        var t = e.target.tryPixelToLocation(p);
        var l = new Microsoft.Maps.Location(t.latitude, t.longitude);

        // Clear and draw polygon with new point //                  
    }
}

How can I get the latitude/longitude of the click when the targetType is Polygon?

When the click event is on a Polygon class use map.tryPixelToLocation as the polygon class doesn't have that function.
