Get cancel event of lookup window in crm 2016

Hi All,

I am opening crm lookup window from html webresource, for this I am using below code

var dialogwindow = new Mscrm.CrmDialog(Mscrm.CrmUri.create(url), this, 500, 400);

dialogwindow.setCallbackReference(CallbackFunction);

dialogwindow.show();

When I am selecting  a record and click on OK. I am able to get record reference in callback function.

But when I am clicking on cancel , callback function does not called.

I want to capture cancel event also. 

Can any one please help me, how to do this.

Thanks,
