I have form in XUL application which collects data and that data is supposed
to be written to RDF file. But there is a problem.Data is shown in tree, but
it is not written to RDF file. Like Flush method doesn't work.Here is
function that collects data and writes it to file:

function dodaj()
 {
var RDF =
        Components
        .classes["@mozilla.org/rdf/rdf-service;1"]
        .getService(Components.interfaces.nsIRDFService);
 var RDFC = '@mozilla.org/rdf/container;1';
 RDFC = Components.classes[RDFC].createInstance();
 RDFC = RDFC.QueryInterface(Components.interfaces.nsIRDFContainer);
 var RDFCUtils = '@mozilla.org/rdf/container-utils;1';
 RDFCUtils = Components.classes[RDFCUtils].getService();
 RDFCUtils =
RDFCUtils.QueryInterface(Components.interfaces.nsIRDFContainerUtils);
 var tablica=document.getElementById("rezultati");
 var source=tablica.database.GetDataSources();
 datasource=source.getNext();
 datasource.QueryInterface(Components.interfaces.nsIRDFDataSource);
 rootnode = RDF.GetResource("urn:root");
 RDFC.Init(datasource,rootnode);
 var newnode=RDF.GetResource("urn:root:knjiga"+(RDFC.GetCount()+1))
 var ISBN=document.getElementById('dodajisbn').value;
 predicate = RDF.GetResource('knjiga#ISBN');
 object = RDF.GetLiteral(ISBN);
 datasource.Assert(newnode,predicate,object,true);
 RDFC.AppendElement(newnode);

datasource.QueryInterface(Components.interfaces.nsIRDFRemoteDataSource).Flus
h();

}

Here is RDF file that is datasource:

<?xml version="1.0" encoding="ISO-8859-2" ?>
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
                xmlns:knjiga="knjiga#" >
<rdf:Seq about="urn:root">
     <rdf:li>
         <rdf:Description about="urn:root:knjiga1">
              <knjiga:ISBN>953-173-826-2</knjiga:ISBN>
         </rdf:Description>
     </rdf:li>

     <rdf:li>
         <rdf:Description about="urn:root:knjiga2">
              <knjiga:ISBN>86-11-04531-9</knjiga:ISBN>
         </rdf:Description>
     </rdf:li>
</rdf:Seq>
</rdf:RDF>

I don't really know what could be the problem, why data is not written to
file?
Thanks!
