Buttons - Bookmarks integration

Hi All,

I  have placed two blank buttons and used boomark to hide/show components at run time. The bookmarks work fine in the bookmark pane, but it does not seem to be working with the buttons. The only property I used for the buttons is the "Action" where I have selected "Type" as Bookmark and "Bookmark" as bookmark name. 

Can someone please help me identify the root cause.

Thanks
