[flexcoders] Using setSyle on dynamic created button not working

[darylgmyers]

I'm creating a number of objects dynamically in actionscript.  then I'm 
using setStyle to set certain styles before addChild actually adds the 
object to the container.  The setStyle is not working.  Below is a 
small piece of the code.

varnewButton:Button = new Button;
newButton.label="Update";       
newButton.setStyle("bottom","10");                              
newButton.addEventListener(MouseEvent.CLICK,clickUpdate);
newHBox.addChild(newButton);
