Facebook Import by button click

Hi,
I’m testing integration with Event Manager plugin so that when I add an event to my facebook page I’d like to import immediately the events to wordpress, instead of waiting until 1 hour for scheduled import.
I see this in settings “We’ll fetch events for you automaticly but you can reload at anytime.” but I don’t understand how.
If I put my event page id again in form and click “import page events” button it says “###pageNumber### already exists.” but it doesn’t import events immediately.

My workaround to try it is

<form id="facebook_event_import_custom" method="post" >
	        <input type="submit" value="Sincronizza ora" class="button-primary"/>
	        <img class="loader" src="<?php echo plugins_url( 'assets/images/X-loader.gif', __FILE__ ); ?>" width="30" heigh="30">
	</form>

in facebook_events_importer.php and I think that the best way to refresh import by clicking a button is to add actionEvent to facebook_import.js like this

$('#facebook_event_import_custom').submit(function (event) {

                $('#facebook_event_import_custom .loader').fadeIn();
                event.preventDefault();
                $.ajax({
                   url: fbeAjax.ajaxurl,
                    type: 'POST',
                    data: {
						action : 'fbe_cron_hourly_event'

                    },
                    success: function (data) {
					    $('#facebook_event_import_custom .loader').fadeOut();
						$('#event_results').html(data);
                        $('#event_results').fadeIn(300);

                    },
                    error: function () {
						$('#event_results').html('error');

                    }
                });

                return false;

            });

But I don’t know if this is correct and what function sets the importing off.

HOW CAN IMPORT IMMEDIATELY FACEBOOK EVENTS?

Thank you for help
