unable to change ahah property of submit button on form rebuild

Hi,

I was working on this module where I needed to change the submit actions of a submit button, after the submit action of another button. Let us say, I have two submit buttons, sb1 and sb2:

$form['sb1'] = array(

'#type' => 'submit',

'#value' => t('sb1'),

'#submit' => array('test_module_sb1_submit'),

);

$form['sb2'] = array(

'#type' => 'submit',

'#value' => t('sb2'),

'#submit' => array('test_module_sb2_submit'),

);

$form['sb2']['#ahah'] = array(

'path' => 'test_module/js',

'wrapper' => 'test_module_replace',

'effect' => 'fade',

);

Now when sb1 is submitted and form is rebuild, I am changing the submit actions of sb2 to these,

$form['sb2'] = array(

'#type' => 'submit',

'#value' => t('sb2'),

'#submit' => array('test_module_sb2_change_submit'),

);

$form['sb2']['#ahah'] = array(

'path' => 'test_module_change/js',

'wrapper' => 'test_module_replace',

'effect' => 'fade',

);

The submit function is successfully changed to 'test_module_sb2_change_submit', but the '#ahah' property of 'sb2' remains the same. Is this the expected behavior or a bug? I could not find any documentation on this. How this can be achieved? How this can be achieved if the first button 'sb1' is also 'ahah' processed?

Thanks, I am attaching the test code for quick look on what I expect and what I get.
