[TYPO3-english] Change tx_news Administration layout

[TSniper]

Hello,

i want to make changes on the news administration layout with mine in fileadmin folder, but the typoscript didn't works.

here the code i added :
module.tx_news {
	view {
		#templateRootPaths >
		templateRootPaths {
			0 = fileadmin/templates/ext/news/Templates/
			1 < .0
		}
		#partialRootPaths >
		partialRootPaths {
			0 = fileadmin/templates/ext/news/Partials/
			1 < .0
		}
		#layoutRootPaths >
		layoutRootPaths {
			0 = fileadmin/templates/ext/news/Layouts/
			1 < .0
		}
	}
	settings {
		orderByAllowed = author,uid,title,teaser,author,tstamp,crdate,datetime,categories.title,starttime
	}
}

in the template object browser, i see my ts code is working but if i change something in the html, i don't see the results in the backend news administration.

did i miss something ?
thanks for any helps.
