Build a Sample App code in the getting started section does not compile

[tripokey]

The code in the Build a Sample App page in the getting started section does not compile.

If the App struct is changed from:
struct App { clicked: bool, onclick: Callback<()>, }

To (also updating the use yew:: to include ClickEvent):
struct App { clicked: bool, onclick: Callback<ClickEvent>, }

The sample app compiles.
