JqueryMobile Cache Ajax issue - html

Question

I have a strange issue with my jquery mobile application. Below screen shot from Chrome Developer Tools Snapshot.
Why does my Pages or Scripts are cached even thiugh Have added
$.ajaxSetup ({
cache: false
});
Also in every ajax call which loads my ul > li have set cache:false.
Kindly let me know how can I overcome this scenario coz of this my Mobile cache is growing on every single click driving me nuts.
Thanks
Update :
Every time I click to navigate to another page this scripts get executed :
$('body').on('click', '.menuClass', function(e) {
e.preventDefault();
e.stopImmediatePropagation();
var menuid = $(this).attr('id');
if (menuid == '100001') {
settings.get('setval', function(obj) {
if(obj.value.tableMode == "1"){
$.mobile.changePage('categories.html', {
transition : "slide"
});
return false;
}
else{
$.mobile.changePage('index.html', {
transition : "slide"
});
}
});
}
});
But for somereasons the URL for categories.html loads on every click changing the url to
below
http://localhost:8080/categories?_=1347279588477
http://localhost:8080/categories?_=1347279584203
http://localhost:8080/categories?_=1347279688227

I don't know why cache:false doesn't work but i'm adding a time created string to prevent caching of ajax pages.
Doing this by adding &ts="+ new Date().getTime() to end of url .
Here is my usage ;
$.ajax({
type: "GET",
url: "ajax.php?ajax_file=ajax_table_page&ts="+ new Date().getTime(),
success: function(data){
..................
}
});
I also use this to trace ajax errors (you may add after document is ready )
$.ajaxSetup({
error:function(x,e){
if(x.status==0){
alert('You are offline!!\n Please Check Your Network.');
}else if(x.status==404){
alert('Requested URL not found.');
}else if(x.status==500){
alert('Internel Server Error.');
}else if(e=='parsererror'){
alert('Error.\nParsing JSON Request failed.');
}else if(e=='timeout'){
alert('Request Time out.');
}else {
alert('Unknow Error.\n'+x.responseText);
}
}
});
