Docs: Homepage example of components is different from Components section, broken

On the [Homepage](https://hyperscript.org/) for Hyperscript, there is an example of using a component structured as:
```html

+
Clicks: ${^count}

```
which doesn't seem to work when I try it in the playground or my own file locally. It also differs from the examples within the Components section:
```html

<button _="on click increment ^count">+</button>
<span class="label">Clicks: ${^count}</span>

```
