I have a issue with being able to link back to the home page from a AJAX response from a Multi-page layout form submission

The structure

`index.php` has multi-page agreement (`index.php#agreement`) 

`#agreemen`t has a form that is using the default AJAX call for submission to (`agreement.php`)

From agreement.php I can go back to the last page (`#agreement`) which is expected but now I wanted to go back to the `index.php` page. 

I can easily put `href="index.php"` but then the session looses it values.

Is there a way to go back two steps? or access the URL history and point to a specific page without loosing any of the data in the form(s)?

I have binded `agreement.php` using this code in `index.php` 

1.     $('#agreement_status').live('pageshow',function(event, ui){
2.         // Button action
3.         $('#back_home').click(function(){
4.             window.history.back(); // this goes back one page to index.php#agreement
5.             window.history.back(-2); // this goes back one page to index.php#agreement
6.             $.mobile.changePage("#index", "slideup"); // this works but appends the hashtag in the URL which breaks the other functionality 
7.         });
8.     });

In agreement.php I have this code

1.     <a id="back_home" 
2.        data-role="button" 
3.        data-icon="home" 
4.        data-theme="z" 
5.        data-inline="true" 
6.        style="float:right;">
7.         Home
8.     </a>
