I want to add simple, custom control (newsletter signup form, which is being rendered with a custom form template). In code below, when returning $formSignup only, everything works fine. When using the renderWith() method the proper action (/home/SignupForm in URL) is being called, but somehow the connection to the page controller is lost. I am not sure what I am doing wrong. The custom form is being send to the browser only completely detached.

	/**
	* This function puts a form on your page, using $Form.
	*/
	public function SignupForm() {
		$formSignup = new Form($this, "SignupForm", new FieldSet(
				new EmailField("Email", "","E-Mail Address")),
				new FieldSet(new FormAction("SignupAction", "Sign up"))//,
				//new RequiredFields("Email")
			);
		//return $formSignup;
		return $this->customise($formSignup)->renderWith(array('FormSignup'));
	}

	/**
	* This function is called when the user submits the form.
	*/
	public function SignupAction($data, $form) {

		// Create a new Member object and load the form data into it
		$member = new Member();
		$form->saveInto($member);

		// Write it to the database. This needs to happen before we add it to a group
		$member->write();

		// Add the member to group. (Check if it exists first)
		if($group = DataObject::get_one('Group', "ID = $this->defaultGroupID")) { 

			$member->Groups()->add($group);
			// Redirect to a page thanking people for registering
			Director::redirect('signup-thank-you/');
			
		} else {
			// Redirect to a failure page
			Director::redirect('signup-failure/');
		}
	}

I appreciate any help.

this may come in handy for anybody who wants to easily include forms in a sidebar or any other area of the site, without controlling a hidden page:

http://www.clickheredigital.co.uk/blog/how-to-include-a-silverstripe-form-on-any-every-page/

it also has an easy "query database for existing member" function that isn't covered in the form tutorials...
