Don't use the updater to show and hide stuff, it's for rendering new content
into the client by making a call back to the server.  That means the content
doesn't exist on the client yet, it's not just hidden, it's not rendered at
all.

To show and hide stuff, use html element not html updater.  

html element id: #someTag; show.

html element id: #someTag; hide.

html element id: #someTag; toggle.

This is also much faster because it simply toggles the display property,
rather than going back to the server.  Just render the content with style:
"display:none" the first time and use the element to show/hide/toggle it.
