how to send table data to odata service

hi sapui5 experts

I'm trying to send the data I have in a table to my odata services but  I don't kwon how to send it...

this is my code:

var oSaberAll = [];  var oSaber = {};  var oTable = oView.byId("oTbMaterias");  var oLIMaterias = oTable.getItems();  $.each(oLIMaterias, function(index,oMateria){  console.log(oMateria);  var oCells = oMateria.getAggregation("cells");  var sNomMateria = oCells[0].mProperties.text;  var sCodMateria = oCells[1].mProperties.text;  var sPuntMateria = oCells[2].mProperties.text;  oSaber.Id = oView.byId("oINumEst").getValue();  oSaber.Type = oView.byId("oSTipId").getSelectedItem().getKey();  oSaber.Subtestid = sCodMateria;  oSaber.Subtestres = sPuntMateria;  oSaberAll.push(oSaber);  });  oSaberAll.Id = oView.byId("oINumEst").getValue();  oSaberAll.Type = oView.byId("oSTipId").getSelectedItem().getKey();
oModel.create("Saber11Set", oSaberAll, null, function(oData, oResponse) {  sap.m.MessageToast.show("Datos guardados correctamente!");  console.log(oData);  },  function(oData, oResponse) {  aSaveEstudio = false;  sap.m.MessageToast.show("Error");  console.log(oData);  });

and here is my Odata entityset

and I get an error in the gateway log that says "Error while parsing an XML stream"

any would be apreciate
