Cant update phantom=true and dirty=true on store data

Hi how can i update my store data Phantom=true and Dirty=true. This may help me to save large data to my store. Currently when i load my 3000+ data in my store it does not save all the data fetch from my ajax call json return.

Below is my code:

Code:

console.log("Loading TEO Frame Count");


            // Also remove all existing records from store before adding
            auditFrameCountTeoStore.getProxy().clear();
            auditFrameCountTeoStore.removeAll();




            var data = Ext.JSON.decode(response.responseText); //encode Json List


            Ext.Array.each(data, function (record) {
                record.phantom = true;
                record.dirty= true;
                auditFrameCountTeoStore.add(record);
            });


            auditFrameCountTeoStore.load({
                callback: function (records, operation, success) {
                    auditFrameCountTeoStore.sync();
                    console.log('TEO DATA: ' + auditFrameCountTeoStore.getData().length);
                },
                scope: this
            });
