We are writing JQueryMobile application using ASP.NET MVC3 + JqueryMobile RC1.
Few pages have their own Ajax methods which we call using jQuery code ($.getJSON()) method.
To invoke these in Ajax calls we do click event bindings inside "pageinit" event of jquery-mobile as mentioned here(http://jquerymobile.com/demos/1.0rc1/docs/api/events.html).
But, call to method binded to pageinit get increased +1 by each visit to the page. e.g. if i visit again to my page using back button or from any other link, visit it again, pageinit method called twice, and any code written inside pageinit executed two times...these keep on increasing with each visit to page.
Which event should we use to bind events. and it should be called only once on page load?
Edit:-
We want default AJAX behavior of JQM and we have kept AjaxEnabled to true.
Sample source Code(you may repro this issue by creating new MVC3 APP and replacing below three .cshtml with given code:-
My _Layout.cshtml:-
<!DOCTYPE html>

<link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
<script type="text/javascript">
$(document).bind("mobileinit", function () {
$.mobile.ajaxEnabled = true;
});
</script>
