I am using Safari browser and I can see the text in the button.  

For better support use `value` attribute to provide support for all browsers.

```html
<div class="btn-group btn-group-lg">
<button onclick="change();" id="face-btn" type="button" value="Face" class="btn btn-primary">Face</button>
```

Hope it helps.
