[Angular2]How to use filereader.load with Angular2 and Typescript?

Try to read a file from client side with Angular2 and Typescript.

But when I try something like: 

fileReader.onload = function(e) {

  ......

}

It doesn't work, this function will never be called. (which works in normal html+javascript.)

Need a solution here, many thanks!!

I finally find a way to build a online example with Typescript.

Check this from an online IDE:

preview:

editor:

https://ide.c9.io/butaixianran/angular2

Again, need a solution for this. Thanks

Here are some examples can easily play with:

First of all:  FileRead with pure javascript, works fine:

With angular2, ES5 javascript (generate by TypeScript), doesn't work:

With angular2 and typescript at codepen:
(Typescript with .t.d file won't work at codepen, following link just show you the TS source code)

Online IDE (c9.io), sandbox with Angular2 and TypeScript, doesn't work:
(can login with github account)

Need a solution, thanks
