Wp-Navi does not work on Homepage

I don’t know what I’m doing wrong but wp-navi does not work on my homepage, when I use the same template as a single Page de wp-navi works.

Here is my code:

<?php

$paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;
$upcoming = new WP_Query();
$upcoming->query( array(
	'post_type'=> 'tribe_events',
	'eventDisplay' => 'upcoming',
	'posts_per_page' => 3,
	'paged' => $paged)
);

if ($upcoming->have_posts()) :
	while ($upcoming->have_posts()) :
		$upcoming->the_post();
		?>

<article <?php post_class('blog-entry clearfix'); ?>>
	<?php
    // Get resize and show featured image : refer to functions/img_defaults.php for default values
    $wpex_entry_img = aq_resize( wp_get_attachment_url( get_post_thumbnail_id(), 'full' ),  wpex_img( 'blog_entry_width' ), wpex_img( 'blog_entry_height' ), wpex_img( 'blog_entry_crop' ) );
    	if($wpex_entry_img) {  ?>
        <div class="blog-entry-thumbnail">
            <a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><img src="<?php echo $wpex_entry_img; ?>" alt="<?php echo the_title(); ?>" /></a>
        </div><!-- /blog-entry-thumbnail -->
    <?php } ?>
    <div class="entry-text clearfix">
        <header>
            <h2><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php if (strlen($post->post_title) > 30) {
echo substr(the_title($before = '', $after = '', FALSE), 0, 30 ) . '...'; } else {
the_title();
} ?></a></h2>
        </header>
       <div class="tribe-events-schedule updated published tribe-clearfix">
		<h3><?php echo tribe_events_event_schedule_details(); ?></h3>
		<?php echo tribe_events_event_recurring_info_tooltip(); ?>
	</div>
		<?php echo custom_field_excerpt(); ?><a class="more" href="<?php the_permalink(); ?>">[+]</a>
             <!--  <span class="date">
        <?php // echo tribe_get_start_date( $post->ID, false, 'l  j F , Y' );?>
               </span>
    </div><!-- /entry-text -->
    <div class="social">
     <?php if( function_exists('ADDTOANY_SHARE_SAVE_KIT') ) { ADDTOANY_SHARE_SAVE_KIT(); } ?>
    </div>
</article><!-- /blog-entry -->

<?php
	endwhile;
	if ( function_exists('wp_pagenavi') ) wp_pagenavi( array( 'query' => $upcoming ) ); // tell it which query we are paginating
endif;
wp_reset_query(); // important to reset the query
?>
