This sounds astonishingly similar to a problem I'm having with 
CellRendererCombo:
http://bugzilla.gnome.org/show_bug.cgi?id=317387 ( see above post )

Basically, CellRendererText is set up so that when the focus leaves the 
editable things, an 'edited' signal is fired. This means that a user can 
type stuff in a cell, and then immediately click outside the TreeView, 
and the changes are detected ( ie the edited signal is fired ).

Unfortunately, this doesn't happen ( automatically ) in other renderers, 
for example CellRendererCombo, and your CellRendererSpinButton. In these 
cases, you have to force an edited signal by pressing the Enter key ... 
or by clicking somewhere else inside the TreeView ( but outside the 
current cell ). In your case, since you only have one cell in the 
TreeView, there's nothing else to click into, so your only way of 
triggering the 'edited' signal is to use the keyboard. If there is some 
way to *make* this happen in code, then I'm all ears :) This issue is 
going to present a large problem for me soon too ...
