Add data attribute to button

[guit4eva]

Hey guys,

Is it possible to add a data-attribute to a button and retrieve that value? Something like:

```

<use id="btn1" data-value="hello" href="#icon-button" class="large-button application-fill plus-button" />

btn1.addEventListener("click", (evt) => {

console.log(this.value); // should print "hello"

});
```

Thanks in advance! 🙂
