switchbutton in form does not send the value

[kandy]

Hi,
I have a form
<form id="formMy" method="post" enctype="multipart/form-data">
<input type="hidden" name="id" id="id"/>
....
<input class="easyui-switchbutton" name="aa" id="aa" data-options="onText:'Yes',offText:'Nooo'" value="1">
</form>

if I set the switch on the variable aa is sent, however, if I do not change it the variable aa is not sent with submit.

The switchbutton is same as checkbox. It has on/off state and can be toggled by the user. When a form is submitted, only the checked components can be submitted.
