Page View Caching Problem in drupal 7

I have a page View and I have been manipulating the data inside the view using ajax. The changes get reflected in the database. The problem is when the page is refreshed, it shows the old cached data, even though I have set caching 'None' in the View .Also, when the cache is flushed, the actual data is displayed and please note that the logged users are using this page view

Can someone help me?

The code for displaying the view is as follows:

function narrative_production_schedule_block_refresh($date) {
$date_str = strtotime($date);
$view = views_get_view('production_schedule');
$view->is_cacheable = FALSE;
$replace_div = '';
if($date == 0) {
$view->set_display('left_block'); $view->is_cacheable = FALSE;
$view->execute();
$view->query->add_where("Left", 'field_data_field_schedule_date.field_schedule_date_value', $value = 0, $operator = '=');
$view->query->add_where("Left", 'field_data_field_schedule_date.field_schedule_date_value', $value = NULL, $operator = 'IS NULL');
$view->query->where["Left"]['type'] = 'OR';
$view->execute();
$result = $view->result;
$replace_div = theme('narrative_production_schedule_leftblock',array('result' =>$result));
}
else {
$args = array(0 => $date_str);
$view->set_arguments($args);
$view->set_display('week_block');
$view->execute();
$result = $view->result;
$replace_div = theme('narrative_production_schedule_block',array('result' =>$result));
}
return $replace_div;
}
