reset button not working in form posting

[eluser]sheri.nust[/eluser]
Hey,

me using form

and inside form i am using reset button

Code:

<input type="reset" name="storeReset" value="reset" />

form tag is

Code:

<form action="<?=base_url();?>index.php/controller_store/store/index/register" method="post" name="storeForm" id="storeForm"  >

so the control goes to controller, and i did validation there, it works fine

Problem is before posting form ,
if I use reset button , it works,
but after form is being posted , i click reset button , it doesn't work.

for each element of form i am using

Code:

<input name="mark_down_price" type="text" id="mark_down_price"
value="<?=$this->input->post('mark_down_price')"/>
