What event is triggered if a google maps drawn circle is moved? - google-maps-api-3

Question

When you draw a circle in google maps api it has a point right in the center of it and when you move the circle by that point(if not by that point i get bounds changed and then center changed events) what kind of event is triggered ?
I have tried "center_changed", "dragend", "bounds_changed", nothing is triggered if circle is moved by that point.
drawingManager.setDrawingMode($scope.G.drawing.OverlayType.CIRCLE);
drawingManager.set('circle',{
strokeWeight: 3,
strokeOpacity: 1.0,
fillOpacity: 0.3,
fillColor: "red",
draggable: true,
geodesic: true,
editable: true,
suppressUndo: true
});
here's the code i set up drawing manager, and after that i just draw a circle on the map.

The DrawingManager won't let you change the center until the circlecomplete event fires. Add a 'center_changed' event listener to the circle when the 'circlecomplete event fires, use that to capture the changes of the center position.
google.maps.event.addListener(drawingManager, 'circlecomplete', function (circle) {
google.maps.event.addListener(circle, 'center_changed', function (e) {
document.getElementById('info').innerHTML = circle.getCenter().toUrlValue(6);
});
});

code snippet:
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(-34.397, 150.644),
zoom: 8
};
var map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
var drawingManager = new google.maps.drawing.DrawingManager({
drawingMode: google.maps.drawing.OverlayType.MARKER,
drawingControl: true,
drawingControlOptions: {
position: google.maps.ControlPosition.TOP_CENTER,
drawingModes: [
google.maps.drawing.OverlayType.CIRCLE
]
},
markerOptions: {
icon: 'images/beachflag.png'
},
circleOptions: {
fillColor: '#ffff00',
fillOpacity: 1,
strokeWeight: 5,
clickable: false,
editable: true,
zIndex: 1
}
});
drawingManager.setMap(map);
google.maps.event.addListener(drawingManager, 'circlecomplete', function(circle) {
google.maps.event.addListener(circle, 'center_changed', function(e) {
document.getElementById('info').innerHTML = circle.getCenter().toUrlValue(6);
});
});
}
google.maps.event.addDomListener(window, 'load', initialize);
