And you can do something like:
<script>
var select_in_var = '<select style="width:300px;" id="province_zone" name="provinceSel"><option value="">select province</option></select>';

var group = new AW.UI.Group;
group.setId("group22222");
group.setControlText("province select");
group.setContent('html', select_in_var );
document.write(group);

var button = new AW.UI.Button;  
button.setControlText('Show contents of group') 
button.setId('a01'); 
  
button.onControlClicked = function(){  
alert( group.getContent('html') );
}   
document.write(button);  
</script>
