title: Milo OPC UA Server push Values in Server Logic
body: <p>I'm a newbie to OPC UA. </p>
  
  <p>My target is to create a OPC UA Server and as soon somebody changes any Value I want to receive a function call, so I can react on the Input.</p>
  
  <p>To archive this, I created a server with MILO-Eclipse. In my Namespace I have some functions called onDataItemsModified() etc. But if I change a Value in my Server with UAExpert, the Server doesn't call the onDataItemsModified() Function. Is there another way to receive a notification as soon somebody changed a value on my Server? I saw the opportunity to add a client and register an observer, but I thought I can see the changes directly as Server and dosnt need to implement a client.</p>
