caching - Cache issue with javascript -

-

i have javascript code detect fields changes on page. working ie unfortunately not in chrome. don't know why happening. when try access via different browsers , units. javascript not working well. need clear cache history make work properly. here's code:

var ctr = 1;     var isfirstload = true;       function propertychangedbycode() {         ctr = 0;         propertychanged();     }      function propertychanged() {         if (document.readystate == "complete") {             $('[id$=savebutton]').removeattr("disabled");             $('[id$=savebutton]').removeattr("class");             $('[id$=savebutton]').addclass("btn btn-primary");             warnmessage = 'warning: have unsaved changes.';              console.log(ctr);              window.onbeforeunload = function () {                 if (ctr == 0) {                     return warnmessage                 }                 else if (ctr == 1) {                     ctr = 0;                 }             }         }     }      $("body").click(function (event) {         console.log(event.target);         if (event.target.type == "submit" && event.target.value != "save" && event.target.value != "cancel" && event.target.value != "next") {             ctr = 0;             propertychanged();             console.log("body clicked");         }     });      function pageload() {          jquery("input.datepicker").dp({             dateformat: 'm d, yy',             altformat: 'yy-mm-dd',             buttontext: '<i class="icon icon-calendar"></i>',             showon: 'both'         });          $("button.ui-datepicker-trigger").addclass('btn right');          console.log("pageonload: " + ctr);          var warnmessage = 'warning: have unsaved changes.';         $('input[type="text"],select,textarea').each(function (k, v) {              var elem = $(this);             // save current value of element             elem.data('oldval', elem.val());              // changes in value             elem.bind("change keyup input paste", function (event) {                 ctr = 0;                 // if value has changed...                 if (elem.data('oldval') != elem.val()) {                     propertychanged();                 }             });         });          $('.btn').click(function (e) {             console.log("whatever");             ctr = 1;         });          //ui-datepicker-trigger         $('.ui-datepicker-trigger').click(function (e) {             console.log("date");             ctr = 0;         });          if (isfirstload) {             window.onbeforeunload = null;             $('[id$=savebutton]').attr("disabled", "disabled")              console.log("disable");              isfirstload = false;         }

so this, decided take on path on disabling caching on system. put code on master page page_load. 

response.cache.setcacheability(system.web.httpcacheability.nocache) response.cache.setnostore() response.cache.setallowresponseinbrowserhistory(true)

base on research, these 3 lines disable caching in application. tried clear cache, inputted values on field, hit save, , browse again page still fields presenting previous input in autofill. i'm assuming disabling of caching won't work. have ideas why disabling of caching not workin? have suggestions regarding browsing caching? , why think i'm experiencing issues need clear cache in order make javascript work properly? lastly, why working on ie not in chrome? thanks! sorry load of questions.
