Made two pages on JQuery Mobile library, put on every page listview. Lists are dynamically generated. But notice if I call the refresh on the invisible list, an error is returned: Uncaught cannot call methods on listview prior to initialization; attempted to call method 'refresh'
A simple solution to update the list is to check with the selector :visible if the listview item is visible. In the example, two dynamic list, on the various pages are updated when the page displayed.

var list1 = list2 = '';
for(i=0;i<5;i++){
list1 += '<li><a href="#list" data-icon="arrow-r">item'+i+'</a></li>';
list2 += '<li><a href="#index" data-icon="arrow-r">item'+i+'</a></li>';
}
$(document).bind("pageshow", function(){
if($("#list1:visible").length){
$('#list1').html(list1);
$('#list1').listview('refresh');
}
if($("#list2:visible").length){
$('#list2').html(list2);
$('#list2').listview('refresh');
}
});
</script>
</head>
<body>
<div data-role="page" id="index">
<div data-role="content">
<ul data-role="listview" id="list1">
</ul>
</div>
</div>
<div data-role="page" id="list">
<div data-role="content">
<ul data-role="listview" id="list2">
</ul>
</div>
</div>
</html>
Or attach a handler of list refresh to the page show event.
