Radmenu Failing to take resource files as radmenu item title

[yishagerew]

I am using radmenu from a sitemap data source in my application.Everything works fine in using a resoource files from  CHUS.en-US and CHUS.en-fr as my application is bilingual.I assign all controls like {txt:home} in the application interface and
<data name="txt:home" xml:space="preserve">
    <value>Home</value>
  </data>
in the global resource files.
Radmenu items display {txt:home}  than the right one as Home.
Any help?
