Listview style issue when changing the page - jquery-mobile

Question

I'm working on a single page application using jquery mobile along with knockout.js binding on MVC4 platform..
This is my button on the main div page:
<div data-role="page" id="pageMain">
<div data-role="content">
View Invoices
</div>
</div>
This is my target div page:
<div data-role="page" id="pageExisting">
<div data-role="header">
<h1>Existing Invoices's</h1>
<a data-rel="back" data-role="button">Back</a>
</div>
<div class="choice_list" data-role="content" data-bind="visible: Headers().length > 0">
<ul id="headersList" data-role="listview" data-bind="foreach: Headers" data-filter-placeholder="Search Invoice" data-filter-theme="a" data-inset="true"
data-filter="true" data-theme="b">
<li>
<a href="#" data-inline="true">
<h2>Invoice No.: <span data-bind="text: inv_no"></span></h2>
<p>Amount.: <span data-bind="text: inv_amt"></span></p>
</a>
</ul>
</div>
</div>
Here is the script section:
var HeaderViewModel = function () {
//Make the self as 'this' reference
var self = this;
self.Headers = ko.observableArray([]);
function GetHeaders() {
//Ajax Call Get All Employee Records
// self.GetHeaders = function () {
$.ajax({
type: "GET",
url: "/api/InvAPI",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
self.Headers(data);
},
complete: function () {
$.mobile.changePage("#pageExisting");
},
error: function (error) {
alert(error.status + "<--and--> " + error.statusText);
}
});
}
self.GetHeader = function () {
GetHeaders();
}
};
$(document).ready(function () {
ko.applyBindings(new HeaderViewModel());
}
When I hit the button "view Invoices" I get a typical Jquery mobile formated listview
but the problem is when I hit the back button and navigate again to the "PageExisiting" div Page I get the list data with no styling..
When viewing page source in both cases, I noticed that on second navigation;
Li tags have not attributes.
I have tried some solutions like: listview refresh, page destroy, page create prior to the line:
$.mobile.changePage("#pageExisting");
with no luck.
I'm stuck here guys and I will appreciate your proposed solutions
Thanks

Answer 1

Refresh list view before showing the page.
$('#pageID').on('pagebeforeshow', function() {
$('[data-role=listview]').listview('refresh');
});
