SPARQL Insert data with data Type

I use jena to insert data. What is the right syntax of data type? ... UpdateAction.execute(request, model); .... This SPARQL can insert to ontology:

PREFIX pre:<http://www.semanticweb.org/ontologies/bookShop.owl#>
PREFIX rdf:<http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX owl:<http://www.w3.org/2002/07/owl#>
PREFIX xsd:<http://www.w3.org/2001/XMLSchema#">

INSERT DATA
{
  pre:TestBook rdf:type owl:NamedIndividual;  
               rdf:type pre:History; 
               pre:creator "TTT";
               pre:title "Test Book";
               pre:hasCurrency pre:US;
               pre:price "10".
}

I need to add the data type decimal by change line:

  pre:price "10"^^xsd:decimal.

It has Error:
