Can I binding data to a.href or other attribute

How can I replace text 'link-url' by data-binding?

``` HTML
way.set("link-text", "this is a link");
way.set("link-url", "http://this.is.a.url/");
<a href="link-url" way-data="link-text"></a>
```

I expects:

``` html
<a href="http://this.is.a.url" way-data="link-text">this is a link</a>
```

but actually it renders

``` HTML
<a href="link-url" way-data="link-text">this is a link</a>
```
