RadTab event OnClick fired in IE

[federico]

I use a RadTab. I create this with code and I add a template :
RadTab __rt = new RadTab();
__rt.TabTemplate = (ITemplate)__megaTab;

This template is a UserControl.

In This userControl i have a table with a label and others controls (images...).
With FireFox if i click in all Template's control, click events are fired. (OnClientTabSelected and OnClientTabUnselected)
With IE click events are fired only if I clicked into Label....

Please help me
