Wp_schedule_event is scheduled to run but not working

I'm trying to get a cron job running from a WordPress plugin I'm writing (it collects all new products and exports them to CSV every day), so the problem is when I put this code in functions.php everything works fine and the code is valid. but from the plugin folder it planned and I can see it (with Cron View Plug-in) but not executed. I found some more questions, but there was no answer. It doesn't seem like it really worked, or something is blocking it. take a look at my code.

function csv_init(){
add_action('my_hourly_event', 'Download_CSV_with_args');
}

function starthere(){
// some code here
    $file = $_SERVER['DOCUMENT_ROOT'].'/wp-content/csv_settings.php';
                            $content = serialize($args);
                            file_put_contents($file, $content);

                        wp_schedule_event( current_time( 'timestamp' ), 'hourly', 'my_hourly_event');

                            $schedule = wp_get_schedule( 'my_hourly_event' );
                            echo  wp_next_scheduled( 'my_hourly_event' ).'<br>';
                        if ($schedule){
                            echo '<h3>The "'.$schedule.'" Cron Job is running..</h3>';
                         }else {
                            echo '<h3>There are no Cron Jobs that running..</h3>';
                         }

}

function Download_CSV_with_args() {
        //execution of my code
}
