Accepted answer
You are using TextBoxes and To remove TextBox value You have to use value instead of innerHTML.

Use
document.getElementById(idPrefix + 'noDataFound').value = "";

It's because a javascript for validation is added to the button and your confirmation javascript happens to get called first with the second validation javascript never being invoked.

You can possibly tweak the javasript to include the validation logic (after setting the button's CausesValidation="false"), but that's rather ugly and probably needs to be specific to the validation involved as well as the control (button causing the validation). Not sure what else to tell you but to take a look at the resulting rendered page source (view source from your browser) and see what works.
