Does not work with Preview 8, Preview 9 and RC1 anymore

[MichaelPeter]

In Preview 8,9 and RC1 the members need to be public and the event handler syntax has changed from onclick=@handler to @OnClick=.

The syntax for async method calls I'm still figuring out.

Blazor has changed a lot since i published this component. I was busy with some other stuffs since last few months so didn't get a chance to update. But i will take a look at it now and update the repo to the latest version of Blazor as early as possible.
