Overview is not updated after SubmitLister event

I created a new event: SubmitListener.afterSubmit
The script is too remove CDATA wrap in the response xml.
if( submit.response == null )
return
def content = submit.response.responseContent
content = content.replaceAll( "<!\\[CDATA\\[", "" )
content = content.replaceAll( "]]>", "" )
log.info( content )
submit.response.responseContent = content


============

After I run a case, I found in the response, CDATA is still there.
But in the script view, I see CDATA is removed.

How can remove the CDATA tag in the Outline view?
