[Pharo] Checkbox

Alexandre BP
Hi,

I have a problem with checkboxes. I'm trying to add a checkbox at each line of a table.
I have tried several things(the last tries are in comments): 

addActionColumn
columns
add:
((WAReportColumn new)
title: '';
valueBlock: [ :row :html | 
html span
with:[
  "checked ifTrue:[BibliList bibliCollection add: row]."
html checkbox
value: checked;
onTrue:[BibliList bibliCollection add: row]
onFalse:[].
"onClick: [checked := true]"
                                                                                "callback:[:value | value ifTrue: [BibliList bibliCollection add: row]]"
                                                                                      ]]).

Unfortunately, nothing seems to work...when I click on the checkbox, nothing happen and my list bibliCollection (which is an OrderedCollection) is still empty.
Thx for your help
