I have polymer-element:
example
By default templates is not allowed to insert html.
This sample is not working, because it\'s not allowed to insert
One way to do this is through a *Changed watcher and setting the .innerHTML the node:
*Changed
.innerHTML
labelChanged: function() { this.$.div.innerHTML = this.label; }
Then, for the case, wrap things up in a custom element that follows the similar pattern: https://stackoverflow.com/a/22208332.
