That's because what you are doing is completely illegal.  You must NEVER 
modify the document directly inside an ipelet, as this completely messes 
up the undo system.

What you need to do instead is to build an undo item t and register it 
using model:register(t).  That will also take care of updating the UI.

Have a look at the existing ipelets to see how this should work.
And of course read http://ipe7.sourceforge.net/manual/lua-ipelets.html
