Filter Events List problem

Hi everyone,

I tried to use filter today-tomorrow but it doesn’t work even if I use it directly 🙁 …
I would like to start from that filter to implement a filter by a single date passed from datepicker, more complex…why this is not working? This should filter for today ( even is just implemented from authors, I would like to understand how to use the filter manually )

add_filter( 'em_events_build_sql_conditions', 'my_em_scope_conditions',1,2);
function my_em_scope_conditions($conditions, $args){
	if( !empty($args['scope']) && $args['scope']=='my_custom_date' ){
		$start_date = date('Y-m-d', current_time('timestamp'));
		$end_date = date('Y-m-d', current_time('timestamp'));
		$conditions['scope'] = " (event_start_date BETWEEN CAST('$start_date' AS DATE) AND CAST('$end_date' AS DATE)) OR (event_end_date BETWEEN CAST('$end_date' AS DATE) AND CAST('$start_date' AS DATE))";
	}
	return $conditions;
}

add_filter( 'em_get_scopes','my_em_scopes',1,1);
function my_em_scopes($scopes){
	$my_scopes = array(
		'my_custom_date' => 'My custom date'
	);
	return $scopes + $my_scopes;
}
