Reset Button Problem

I have a search page where i have like 10 combo boxes and some radio buttons and check boxes.

Now when the page loads, i do some selection in the combo boxes and when i press reset button it clears all data in the form elements.

But when i select things in combo boxes and do a search by clicking OK button then the search results are displayed there and now if i want to clear all the form elements , i tried to click reset button, but when ever i did a search ie click ok button and after than press reset button reset button is not clearing the form elements.
