Custom delete method doesn't call in custom datasource - php

Question

I'm using a custom datasource to consume webservice.
Create, Read and Update work well but Delete doesn't works.
Here is my code calling the delete method in my controller.
public function delete($id){
$this->autoRender = false;
debug($this->Article->delete($id));
}
And here the code in my datasource
public function delete(Model $Model, $id = null) {
echo "Display a message if this method is called";
$json = $this->Http->post(CakeSession::read('Site.url') . '/webservice/delete/', array(
'id' => $id,
'apiKey' => $this->config['apiKey'],
'model' => $Model->name
));
$res = json_decode($json, true);
if (is_null($res)) {
$error = json_last_error();
throw new CakeException($error);
}
return true;
}
But when I want to delete an item, the debug(); display false.
I have no other displays.
I don't understand why my delete method isn't called correctly.
Is there something wrong in my code ?
Thanks

Let's check: you're only passing a parameter to your method:
$this->Article->delete($id)
According to the method that you created, the first parameter, which is required, is the Model. The second is $id:
public function delete(Model $Model, $id = null)
During the method you want to use both parameters. Here:
'id' => $id
And here:
'model' => $Model->name
Based on this, you need to review how this method will be called. BTW, if you want override delete() method, according the book, you need something like this: delete(int $id = null, boolean $cascade = true).
