How to add custom function for a Button in hwc?

Hi Guys,

    Can anyone please help me in creating a customised function for the button in my workflow.

Actually initially i generated a workflow which gets the MBO details.It worked fine.Then i changed the version of .js and .css in my  workflow's_jQueryMobileLookAndFeel.html file to get a better UI.

     The UI changed.The controls looked much better.

     But Now the control(Button) in my workflow stopped working.

The changes i made were as follows:

I replaced .js files from:

          <script src="js/jquery/jquery-1.5.2.js"></script>

        <script src="js/jquery/jquery.mobile-1.0a4.1.js"></script>

to:

          <script src="js/jquery/jquery.js"></script>       

        <script src="js/jquery/jquery.mobile-1.2.0.js"></script>

simillarly for .css files from :              

          <link rel="stylesheet" href="css/jquery/jquery.mobile-1.0a4.1.css" type="text/css" />

to:

        <link rel="stylesheet" href="css/jquery/jquery.mobile-1.2.0.css" type="text/css" />

I want my workflow to work under this version of jQueryMobile.

How to make our control work.

Any help will be appreciated.

                    Thanks.
