Hello,
I have a need to call a function from template (html) with 1 parameter.

Here is the thing: I have a LOTDpage page type (LOTDPage.php: LOTDPage extends Page; LOTDPage_Controller extends Page_Controller), it is used for displaying LOTDs (lotd is DataObject - LOTD.php: LOTD extends DataObject).

The function for catching all LOTDs goes like this (it is in LOTDPage.php):

function getLOTDs () {
return DataObject::get('LOTD',"","Created DESC","","");
}

and in template I am calling it by (LOTDPage.ss):

<% control getLOTDs %>
<li>
<a href="$LOTD">$LName</a>
</br>
<% if Top.canDelLOTD %>
<a href="LOTD/delLOTD/$ID">Brisanje</a>
<% end_if %>
</li>
<% end_control %>

OK. now the problem. In this case LOTDPage.php also contains function delLOTD:

function delLOTD($request) {
$param = $request->allParams();
$LOTDID=(int)$param['ID'];
DB::query("DELETE FROM LOTD WHERE ID = '$LOTDID'");
Director::redirectBack();
}

Clicking on 'Brisanje' on my page for some reason results in deleting the wanted LOTD from MySQL database, but I don't understand how and why... (I want it to do just that, but I don't understand how it works)
On similar example (I won't type it all over again, it's the same thing but instead LOTDPage.php is RSSPage.php, LOTD.php is MyRSS.php and delRSS($request) instead delLOTD($request) - <a href="/MyRSS/delRSS/$ID">) it doesn't work.
What I need is to be able to call the delete function for any DataObject from <% control %> block by passing the $ID of the current DataObject so I can delete the right one.
How is it done? What is the logic behind <a href="/LOTD/delLOTD/$ID"> Why does it work? Why <a href="/MyRSS/delRSS/$ID> doesn't work? Is there a better way to do it? I need it to be done either from <a href="" onclick=""> or from <BUTTON... onclick=""> or sth simmilar. The idea is do [function($ID)] on [DataObject['ID']] when click (link or button or whatever) from page on my site.

Hope you guys understand what I need and you can help me!
Ty all in advance!
