Reloading the page will reset the filters. But there should be some sort of button as well. This button would need javascript attached that populates all the fields in the form to their default value and (if the current on change doesn't pick this up already) trigger an on change event for one of the fields - this on change event should trigger the ajax call to get the new data.
