Since the downcast is explicit (using "as") the type will be checked even in unchecked mode, so technically there is a slight risk of breakage. But since the callback is so near the creation of the ButtonElement, I'm not concerned. Also, I'm not concerned about the performance penalty of the explicit downcast because the cost is only paid once per user click.
