According to this post the controller action must be smth. as following:

$data=Location::model()->findAll('parent_id=:parent_id', 
              array(':parent_id'=>(int) $_POST['country_id']));

$data=CHtml::listData($data,'id','name');
foreach($data as $value=>$name)
{
    echo CHtml::tag('option',
               array('value'=>$value),CHtml::encode($name),true);
}

Obviously, when you update the DOM element in view id='updatedDivision' with something also having id='updatedDivision' from controller:

echo CHtml::dropDownList('updatedDivision','',array('1'=>'hello','2'=>'2'),array());

it won't work as desired.

Try this in controller/action:

foreach(array('1'=>'hello','2'=>'2') as $value=>$name)
{
    echo CHtml::tag('option',
               array('value'=>$value),CHtml::encode($name),true);
}

Update

Also check with web tools (F12, Ctrl+Shift+I) if an ajax XHR is properly formed and response is sent back.
