Checkboxes do not retain value attribute

[Beanow]

The checkbox fields do not retain the value attribute. This is done throughout the core. Tried:
$(':checkbox').val('someval');
$(':checkbox').attr('value', 'someval');
$(element).html('<input type="checkbox" value="someval" />');

All of which results in a DOM where only they value key is added as a flag (<input type="checkbox" value />).

My mistake. In jsFiddle this does not occur. There's bound to be a conflicting event.
