Nested ListView In Jquery Mobile with mvc - asp.net-mvc

Question

I create nested list view in Asp.net mvc with jQuery mobile, it has 2 sub view, when i navigate to first subview1 i can return back to main view, but when i navigate from subview1 to subview2 i can not back to subview1, since subview1 is somehow null.
in my layout page i put this script
<script>
$(document).on('mobileinit', function () {
$.mobile.page.prototype.options.addBackBtn = true;
$.mobile.page.prototype.options.backBtnText = "Back";
$.mobile.page.prototype.options.backBtnTheme = "a";
$.mobile.defaultPageTransition = "slide";
});
</script>
the main page is :
<script>
$(document).on('click', '[data-rel=back]', function (e) {
e.preventDefault();
var activepage = $.mobile.activePage.attr("id");
if (activepage == "schedule")
$.mobile.changePage($('#flight'), { transition: "slide", reverse: false });
if (activepage == "dayFlight") {
$.mobile.changePage($('#schedule'), { transition: "slide", reverse: false });
}
});
<div data-role="page" id="flight" data-add-back-btn="true">
<div data-role="content">
<ul id="flightListView" data-role="listview" data-inset="false" data-filter="true">
#foreach (var item in Model)
{
<li>
<a href="#Url.Action("Schedules", new { from = item.DepartureFrom, to = item.Destination })" data-direction="reverse" data-transition="slide">
<span class="ui-li-count ui-btn-up-c ui-btn-corner-all">#item.NumberOfFlights</span>
</a>
</li>
}
</ul>
</div>
the subview1 is:
<div data-role="page" data-add-back-btn="true" id="schedule">
<div data-role="content">
<ul id="scheduleListView" data-role="listview" data-inset="false" data-filter="false">
#foreach (var item in Model)
{
<li>
<a href="#Url.Action("DayFlights", new { from = from, to = to, date = item.Date })" data-direction="reverse" data-transition="slide">
<span class="lg">#Html.DisplayFor(modelItem => item.Day)</span>
<span class="lg number laligned">#Html.DisplayFor(modelItem => item.Date)</span>
<span class="ui-li-count ui-btn-up-c ui-btn-corner-all">#item.Nof</span>
</a>
</li>
}
</ul>
</div>
the subview2 is :
<div data-role="page" data-add-back-btn="true" id="dayFlight">
<div data-role="content">
<ul id="dayListView" data-role="listview" data-inset="true" data-filter="false">
#foreach (var item in Model)
{
<li>
<a href="#item.AgencyUrl" rel="external" data-ajax="false">
<span class="ui-li-count ui-btn-up-c ui-btn-corner-all">#item.Cap</span>
</a>
</li>
}
</ul>
</div>
something that i figure out, it is when i navigate to subview1, the mainview and the subview1 both of them are in DOM but then when i navigate to subview2, subview1 will replaced by subview2, so it means when i am at subview2 the subview1 does not exist in DOM.
in all cases $.mobile.activePage.prev('.ui-page'); return null, that is the reason why i decided to use if clause to determine to which page i should navigate back to, however when i want to navigate back from subview2 to subview1 it does not work.
how can i implement this senario?
thanks in advance
