Structure of Jquery mobile

Hi i am new to Jquery Mobile and need to code for creation of a particular app due to which i need to know about how to go about it, i have gone through the design and theming part and have successfully completed the design.Just started coding:
<script type="text/javascript>
 $(document).bind("mobileinit", function () {
            $.mobile.autoInitializePage = false;
            $.mobile.defaultPageTransition = "fade";
            $.mobile.loadingMessage = "Please wait";
        }
    );
</script>
does every page need to start like this... nothing happens when this is applied! Do comment on the above
