Filled form submission in PDF Format using Adobe Reader XI

I have designed form in Adobe LiveCycle Designer ES2 with an email submission button, but when I fill the form & try to submit it using Adobe Reader XI, on click event nothing happens, & when I open the same form in Adobe Acrobat X pro submission button works & sends the filled form in PDF format. & when I changed it to email submission button in design mode it sends file in XML format, but when I change format to PDF in XML source code editor, nothing happens on Click Event.      

So All I want is to submit my filled form in pdf format using Adobe Reader XI.

Please suggest a solution. Any help is highly appriciated. Thanks
