Answer 1

        $script = 'alert("hello")';
        Yii::app()->getClientScript()->registerScript('#test', $script,CClientScript::POS_HEAD  );
        echo CHtml::button('Add',array('class'=>'addfield-button','background-style'=>'none','onclick'=>$script));

if you real want to use Yii style, you can open framework code and there is a good code that you want, search : CButtonColumn.php
