Why are hooks (except hook_help) not working? &lt;?php
function webformta_init() {
    dsm('hello world');
}


does absolutely nothing. 

&lt;?php
   dsm('hello world');


sets an alert message with the text "hello world".

I've tried wrapping this in several hooks. Hook_load, hook_node_load, you name it.

But somehow, oddly, hook_help seems to be working. 

function webformta_help($path, $arg) {
  switch ($path) {
    case "admin/help#webformta":
      return '&lt;p&gt;'.  t("Grades quizzes like a TA. Works with Webform.") .'&lt;/p&gt;';
      break;
  }
} 


creates a nice little help link in the module list and outputs the text and everything.

What did I screw up?
You need to clear the cache after adding new hooks.
