How do you make a button in Bootstrap 3 undepress automatically after being clicked?

To replicate my problem, make a page with some buttons, give them appropriate bootstrap classes (and include bootstrap):

<input id="one" type="button" class="btn btn-default" value="one"> <input id="two" type="button" class="btn btn-primary" value="two">

Load the page and click on one of the buttons. It becomes depressed and highlighted until you click somewhere else on the page (using FF29 and chrome35beta).

Inspecting the input element while clicked and unclicked doesn't show any additional classes being attached and removed from it.

Here's an example of Bootstrap buttons staying depressed: http://jsfiddle.net/52VtD/5166/
