I'm quite new to polymer so this might be a stupid question, but how do I change the content inside this button elmement?

When I create an Element I would write:

<paper-toggle-button checked>Button 1</paper-toggle-button>

and it works great, but how can I programmaticly change the 'Button 1' text?
I searched here: https://elements.polymer-project.org/elements/paper-toggle-button
And tired:

let b = document.createElement('paper-toggle-button');
b.innerHTML = 'My custom text';
document.body.append(b);

But this overrides the internal dom inside the button..

I want to use d3 to create these Elements dynamically.

Thanks.
