OnChange event in Interactive Service Hub

Hello,

Currently im fighting with Interactive Service Hub  and Javascript.

I wrote a small script to display fields and delete field data depending on the settings made on a “two option field” (requestertype).

It works fine within the normal Web-Gui, within the Interactive Service Hub it looks like the event is just fired once.

I was adding the same javascript webresource to the standard form and to the the form of interactive experience (on control “requestertype”).

Anyone has an idea what could be the problem ?

Thanks and best regards,

Ralph

Code:

function OnChangeRequesterType()

{

    var requestertype = Xrm.Page.getAttribute("requestertype").getValue();

       if (requestertype == false) // if internal requester

       {

        Xrm.Page.getAttribute("requesterexternal").setValue(null); //deletes field external requester

             Xrm.Page.getControl("internalrequester").setVisible(true); // show field internal requester

             Xrm.Page.getControl("requesterexternal").setVisible(false); //hide field external requester

       }

       if (requestertype == true) // if external requester

       {

        Xrm.Page.getAttribute("internalrequester").setValue(null); //deletes field internal requester

             Xrm.Page.getControl("requesterexternal").setVisible(true); // show field internal requester

             Xrm.Page.getControl("internalrequester").setVisible(false); //hide field external requester

       }

}
