jQuery Mobile: Uncaught TypeError: Cannot read property 'jQuery...' of undefined

I've got a jQuery Mobile project which is distributed in different files, e.g.

<!DOCTYPE html>
<html>
    <head>
        <script type="text/javascript" charset="utf-8" src="cordova-2.3.0.js"></script>
        <link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" />

        <link rel="stylesheet" href="css/custom.css" />

        <script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
        <script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
        <script src="js/methods.js"></script>
    </head>
    <body>
        <!-- Termine Page -->
        <div data-role="page" id="firstPage">
            <div data-role="header" data-position="fixed">
                <h1>Header 1</h1>
                ...
            </div><!-- /navbar -->

            <div data-role="content">
            ...
            </div>
        </div>
    </body>
</html>

secondPage.html

<!DOCTYPE html>
<html>
    <head>
        <script type="text/javascript" charset="utf-8" src="cordova-2.3.0.js"></script>
        <link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.css" />

        <link rel="stylesheet" href="css/custom.css" />

        <script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>
        <script src="http://code.jquery.com/mobile/1.2.0/jquery.mobile-1.2.0.min.js"></script>
        <script src="js/methods.js"></script>
    </head>
    <body>
        <div data-role="page" id="pageTwo" class="ui-page">
            <div data-role="header" data-position="fixed" id="terminDetailSeiteHeader">
            <h1>Header 2</h1>
        </div>
        <div data-role="content">
                <div id="contentToFillWithDynamicListView"></div>
            </div>
        </div>
    </body>
</html>

Then, I got a script which should make a call to a php-Script and generate a listview:

function listViewCreation() {
    var url = 'http://www.myServer.com/myPhp.php?someParameters=1&callback=?';
        $.getJSON(url, function(data) {
            $('#contentToFillWithDynamicListView').empty();
            var collapsibleList = '<ul data-role="listview">';
            var myselfIsIncluded = 0;
            $.each(data, function(key, value) {
                collapsibleList += '<li>' + value['displayName'] + '</li>';
            });
            collapsibleList += '</ul>';

            $('#contentToFillWithDynamicListView').html(collapsibleList).trigger('create');
        });
    }

The .trigger('create') leads to the error... what am I missing?

EDIT 1

listViewCreation is called the following way:

$("#pageTwo").live("pageshow", function(e, data){
    listViewCreation();
});

EDIT 2 I'm fetching remote data from a different server, that seems to be the reason for the error; but I don't know how to solve it... I'm fetching data on both pages (1 and 2); for the first page it works, for the second it doesn't...

$.getJSON(url, function(data) {
    ...
}

I can see you are using last stable version of jQuery mobile.

Your problem is 

trigger('create');

it is not used for jQuery mobile listview restyling. You should use :

.listview('refresh');

instead. Don't trust official jQM documentation, trigger('create') should be deprecated. Every jQM widget has a function meant to refresh it, for example button('refresh').

Also don't use trigger('create') when changing header, footer or content, it won't work, you can trigger pagecreate on the page: 

trigger('pagecreate');

EDIT :

In case of:

Uncaught Error: cannot call methods on listview prior to initialization; attempted to call method 'refresh'

Call:

$('#listviewid').listview().listview('refresh');

First call will initialize it and second one will style it.
