Data attributes doesn't get updated in DOM after changing

[carloslancha]

Using, for example, a ClayButton:

var button = new ClayButton({
   data: {
      title: 'My Button Title',
   },
   label: 'My Button',
});

The result is:

<button class="btn btn-primary" type="button" data-title="My Button Title">My Button</button>

if you change the button data the DOM element it's not getting updated with new data:

button.data.title = 'My New Title';

Expected result:
<button class="btn btn-primary" type="button" data-title="My New Title">My Button</button>

Current result:
<button class="btn btn-primary" type="button" data-title="My Button Title">My Button</button>
