Won't call click event

This is what I need to do:

1) When first load page show domaines in panel pnlDomainView and put them into array of LinkButton lblDom

2) If I click on a LinkButton from lblDom show thesaurus of that domain and put them into lblThes.

1 and 2 work OK. Problem happends here:

3) When I clik on a LinkButton from lblThes it should call clickThes. But it only calls Page_Load and shows Domaines, won't call clickThes

Application is on this link:
