Fail to get mouse move event

[Mickyjames]

I'm using google closure library and registering for click and mouse move event. I get the click event, however Mouse move event doesn't come. This is observed for Chrome browser, get the same event in Firefox

<canvas id='canvas1' width="512px" height="512px" style='top:0px;right:0px;' > </canvas>

MyTest.virtualCanvas = function(){
this.destCanvas = document.getElementById('canvas1');
this.destCtx = this.destCanvas.getContext('2d');


this.getCallBackFn = this.highContrastFn.bind(this);
this.mouseMoveBackFn = this.mouseMoveCB.bind(this);

goog.events.listen(this.destCanvas, goog.events.EventType.CLICK, this.getCallBackFn);
goog.events.listen(this.destCanvas, goog.events.EventType.MOUSEMOVE, this.mouseMoveBackFn);


};



MyTest.virtualCanvas.prototype.mouseMoveCB = function(evt){
var x = evt.offsetX;
var y = evt.offsetY;

}

MyTest.virtualCanvas.prototype.highContrastFn = function(evt){
var x = evt.offsetX;
var y = evt.offsetY;

}
