$('body').zoomTo() not resetting.

[tograh]

I need to expose a button elsewhere on the page that will restore the zoom to the default. The recommendation that I'm hearing is that I should use $('body').zoomTo().

Using the github example in examples/scrolling/index.html, I added the zoomTarget class to body and appended the following button:

<input type="button" value="press" onclick="{$('body').zoomTo();}"/>

It never has an effect.

Am I doing something wrong?
