I didn't test your code, but I think the problem comes from the way you
index your controls and how you use this index to remove them.
You use the index "i", which should reflect the number of created controls,
in their names. Then use the name to get the index back and use the
index with "removeChildAt".
Let's simulate this:
1. We add 4 controls: btn_ajout0, btn_ajout1, btn_ajout2, btn_ajout3 and i=4
2. Remove one in the middle (say btn_ajout1): btn_ajout0, btn_ajout2,
btn_ajout3 and i=3
3. Now you are in an inconsistent state: btn_ajout0 (child 0), btn_ajout2
(child 1), btn_ajout3 (child 2)
4. If you try to remove btn_ajout2 you wil actually remove btn_ajout3 and if
you try to remove btn_ajout3 you will get the index out of bounds error!
Another possible bug: What if you have more than 10 controls? s.charAt(9)
won't work anymore!
Hope this helps!
