is_home doesn't work

Hi everybody,
I have a problem with my website, i want to show my slider only on the homepage. So i use this:
<?php if( is_home() ) {do_action('slideshow_deploy', '23');} ?>
on my page file and i define my static homepage.
But it doesn’t work.

This work well before, in doubt i upgraded my wordpress to 3.8 and my plug in “slideshow” to 2.2.19.
I tried to add <?php wp_reset_query(); ?> before my condition.

Did you have any idea to help me?
Thanks for your help.
