Button docs say there is a click callback

The button docs bundled with 1.8rc1 [1] define a click event. You should be able to set it as an option. The example uses:

$('.selector').button({
   click: function(event, ui) { ... }
});

This doesn't work work for me. But I can bind a function to the click event with bind() as follows:

$('.selector').bind('click', function(event, ui) { ... });

Two test cases are attached. Though I'm not sure if they belong to the events or to the options tests.

Are the wiki docs keep in sync with the bundled docs? In the wiki the click event is missing [2].
