Title: Fix space key handling

The button's onclick event will fire both for mouse clicks and when the space key is pressed while the button has focus.

**Test case**:
Open a confirm dialog then tab to focus the **Cancel** button then press space key, the **Ok** event will be triggered.

Issue #12 is no longer valid, as PR #33 maintains tab focus inside the dialog until an action happens.
