SharePoint 2013 Javascript Error

I am trying to access sharepoint 2013 list data. Below is the code. This code perfectly works in Chrome. However, when it doesnt work in IE 9. The strange thing is, no errors are logged in console. Also once i press f12 in IE, my code starts working.

function retrieveListItems(){var siteurl =;// a url is herevar clientContext =new SP.ClientContext(siteUrl);var oList = clientContext.get_web().get_lists().getByTitle('ResourceAllocator');var camlQuery =new SP.CamlQuery();
            camlQuery.set_viewXml('<View><Query><Where><Geq><FieldRef Name=\'ID\'/>'+'<Value Type=\'Number\'>'+1+'</Value></Geq></Where></Query></View>');this.collListItem = oList.getItems(camlQuery);

            clientContext.load(collListItem);

            clientContext.executeQueryAsync(Function.createDelegate(this,this.onQuerySucceededs),Function.createDelegate(this,this.onQueryFaileds));}function onQuerySucceededs(sender, args){var allResourceNAme =[];var listItemInfo ='';var listItemEnumerator = collListItem.getEnumerator();while(listItemEnumerator.moveNext()){var oListItem = listItemEnumerator.get_current();//process the data}
