update_field on hook or click?

Hello, I have the following code:

$repeater = get_field('itinerary');
    $count = count($repeater);
    for($i = 0; $i < $days; $i++) {
    $field_key = "field_5ee8665e2cd7f";
    $value = get_field($field_key);
    $value[] = array("testing" => "$array[$i]");
    update_field( $field_key, $value ); }

Which basically loops through a dynamic variable ($days) and then sets the value of that field to the corresponding number in an array.

This works well, but I need to force refresh the page in order to see it. How do I attach this code to the update of the front end form?

Thanks!
