Custom Action With JavaScript

Hello,

•  I have created a java script in layouts folder. This file contains function called "Test".
• Then I create the following custom action:

          <CustomAction
       Id="ArticlesListItemsAction"
       ScriptSrc="~SiteCollection/_layouts/VGSP.VIS.MediaCafe2/ArticlesListItemsCustomAction.js"
       Title="View Comments"
       Description="Show comments for article"
       RequireSiteAdministrator="FALSE"
       RegistrationType="ContentType"
       RegistrationId="0x01001024C2BBEEFB4DDA9AA2AD73150109A1"
       GroupId="ActionsMenu"
       Sequence="1000"
       Location="EditControlBlock">
    <UrlAction Url="javascript:Test();"/>
  </CustomAction>

• I Deploy the solution . Then I navigate to list . Then open the menu of an item of List . Then when press on link , the function not called .

         So what is the problem?

     Thanks
