javascript - How to register event handlers for TypeScript declarations -

i've asked question on typescript's codeplex forums didn't answer i'm asking here. given typescript class declaration, example bing maps 1 (https://bingmapsts.codeplex.com/) how register event handler?

on map class (in microsoft.maps.d.ts) there couple of events declared:

viewchange: () => any; viewchangeend: () => any; viewchangestart: () => any; 

and i've tried hooking function following inside typescript file never gets called:

///<reference path="bing/microsoft.maps.all.d.ts" />  window.onload = function() {     var map = new microsoft.maps.map(document.getelementbyid('map'),         {             backgroundcolor: 0,                         });      map.click = () => alert('click');     map.viewchangestart = () => alert('viewchangestart'); } 

in traditional javascript, use following:

microsoft.maps.events.addhandler(map, 'viewchangestart', function (e)     {         alert('viewchangestart');     }); 

but there no such method in typescript declaration , since can't seem reference virtual earth map control .ts file i'm not sure how can this.

the definition (https://bingmapsts.codeplex.com/sourcecontrol/latest#bingts.solution/bingts/bing/microsoft.maps.d.ts) wrong : http://msdn.microsoft.com/en-us/library/gg427609.aspx functions not exist. can register events via addhandler. simple definition:

declare module microsoft.maps.events{     function addhandler(map:microsoft.maps.map,event:string,func:function); }
