pagination with genesis_after_endwhile

[hp]

I have this function, but there is no pagination. I have 5 posts in this category, and posts_per_page is 3. Wondering if I am doing something wrong? Please suggest. Thank you.

function camnghi() {

  if ( get_query_var( 'paged' ) ) { $paged = get_query_var( 'paged' ); }
  elseif ( get_query_var( 'page' ) ) { $paged = get_query_var( 'page' ); }
  else { $paged = 1; }

  $args = array ( 'cat' => '987',
                'paged' => $paged,
                 'posts_per_page' => '3'
                );

  $wp_query = new WP_Query( $args );
  if ( $wp_query->have_posts() ) :
      $i=1;
      while ( $wp_query->have_posts() ) :
          $wp_query->the_post();
          echo '<div class="luubut-wrap">';
            if ( $i%2 ) {
              echo '<div class="one-fourth first">';
                the_post_thumbnail();
              echo '</div>';
              echo '<div class="three-fourths">';
                the_content();
                echo '<span class="ten-luubut">'.get_the_title().'</span>';
              echo '</div>';
            }
            else {
              echo '<div class="three-fourths first">';
                the_content();
                echo '<span class="ten-luubut">'.get_the_title().'</span>';
              echo '</div>';
              echo '<div class="one-fourth">';
                the_post_thumbnail();
              echo '</div>';
            }
          echo '</div>';
          $i++;
      endwhile;
      do_action( 'genesis_after_endwhile' );

  endif;
  wp_reset_postdata();

}

Found the reason. Need to have "global $wp_query;" first. However, now, the page 2 shows 404 error. Any idea, please?

Thanks.
