wp_redirect and is_page_template is not working?

I am trying to detect the page of the user and then redirect based on that, just of testing purposes now since i want to verify user role and if they are a certain role they will be redirected out from the page. Anyway the following code is not working despite research and trial and error:

function wpse12535_redirect_sample() {

    if(is_page_template('list-projects.php')) {
        wp_redirect('http://ift.tt/2nFpIxN');
    }

}

add_action( 'init', 'wpse12535_redirect_sample' );
