WP_Query returning wrong result

My plugin adds a custom post type to wordpress, and id like to display all posts that have been published. I use wp_query to display all posts but it seems to fetch all post regardless of their status. Have I forgotten something ?

Note that status changes from publish to draft, I use wp_update_post() to edit the post status . here is my code :

Loop :

function jobs_list_loop() {
    global $paged;
    //$curpage = $paged ? $paged : 1;
    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(
        'post_type' => 'job',
        'orderby' => 'ID',
        'posts_per_page' => POST_PER_PAGE,
        'post_status' => 'publish',
        'paged' => $paged
    );
    $query = new WP_Query($args);
    $curpage = $paged;
    if($query->have_posts()) : while ($query->have_posts()) : $query->the_post();
    ?>
    <div id="post-<?php the_ID(); ?>" class="quote">
    <?php
    echo get_the_post_thumbnail($post->ID, array($image_width,$image_height));
    the_content();
    ?>
    </div>
    <?php
    endwhile;
        echo '
        <div id="wp_pagination">
            <a href="'.get_pagenum_link(1).'">?</a>
            <a> 0 ? $curpage-1 : 1)).'">?</a>';
            for($i=1;$i<=$query->max_num_pages;$i++)
                echo '<a href="'.get_pagenum_link($i).'">'.$i.'</a>';
            echo '
            <a>max_num_pages ? $curpage+1 : $query->max_num_pages)).'">?</a>
            <a>max_num_pages).'">?</a>
        </div>
        ';
        wp_reset_postdata();
    endif;
}

Here is the code used to change status from publish to draft :

$jb_post = array(
      'ID' => $id,
      'post_status' => 'draft'
  );
  wp_update_post( $my_post );

Note that if I change to query to fetch only drafts, or trash or whatever it will do it successfuly. Am i forgetting something ? I have made tons of research and can’t find anything giving a suitable answer.

Thank you.
