When hooks are executed?

Following the scarce documentation(click), I created a module foo.module containing the following code:

function foo_views_api() {
  watchdog('foo','bar',false,WATCHDOG_DEBUG);
  return array(
    'api' => 3.5, 
    'path' => drupal_get_path('module', 'foo'),
  );
}

.. and a foo_views.inc file with the following code:

function foo_views_query_alter(&$view, &$query) {
   watchdog('foo_inc','bar_inc',false,WATCHDOG_DEBUG);
   dpm($view);
}

When I load a panel with a view embedded in it, it doesn't execute the function in the .inc file - in fact, none of the views-hooks are executed. What am I doing wrong? When are the hooks supposed to run?

(I use Views 3.5, and Devel enabled)
