Does not work when view is inserted on a page

I created a view and then displayed it as a page : it works fine (on Safari and OmniWeb).
I then created a bloc display to integrate a view on a page : it does not work because scrollable' javascript files are not present.

Here follow the code from the template file.

Working case

...
<div id="contenuPrincipal" class="hauteur_commune">
   <?php print $content; ?>
</div>
...

Non working case

...
<div id="contenuPrincipal" class="hauteur_commune">
   <?php print views_embed_view('boutique', $display_id = 'bloc'); ?>
</div>
...

Code source investigation reveal 2 missing javascript files :

• jquery.mousewheel.min.js
• jquery.scrollable.min.js
