[TYPO3-project-formidable] how to clear (reset) SEARCHFORM ?

[Valery Romanchev]

Hi

I am tryng to create "Clear Filter" button for SEARCHFORM, in the 
situlation like in this example 
http://formidable.typo3.ug/pastebin/snippet/12.html

I just need to reset current values of the SEARCHFORM, so LISTER will 
show all results.


I try to put

<renderlet:SUBMIT name="btn-clear" label="Clear Filter" mode="clear" />

and look to source code and documentaion on the problem, but no success.

May be some php code needed to reset SEARCHFORM values, or may be some 
client side events with BUTTON must be created...

Please put me in the right direction

Thank you in advance
