DataModel Binding Anomaly

Hi, I have a dropdownbox:

new sap.ui.commons.DropdownBox("employeeContractType-dropdownBox", {
  visible: "{oUIProperties>/contract/visible/contractType}",
  enabled: "{oUIProperties>/contract/enabled/contractType}",
  required: "{oUIProperties>/contract/required/contractType}",
  displaySecondaryValues: true,
  selectedKey: "{ContractElementsData>/Contrtype}",
  value: "{ContractElementsData>/ContrtypeName}",
  searchHelpEnabled: true,
  searchHelp: function(oEvent) {
  layoutData: new sap.ui.layout.GridData({
  span: "L4 M4 S6",
  linebreak: false
  change: function() {

After I create the dropdownbox I call oData webservice and set the model to my form

var oContractElementsModel = new sap.ui.model.json.JSONModel();"/ContractDetailsHRSet('" + employeeCode + "')", {
  async: false,
  success: function(oData) {
  myForm.setModel(oContractElementsModel, "ContractElementsData");
  error: function(oError) {
  console.log("Error reading ContractDetailsHRSet: ");

Now after i set the model i want to read the VALUE of my Dropdownbox by reading the datamodel property ContrtypeName. But for some reason it returns undefined although when I console the whole model using myForm.getModel("ContractElementsData") right before I read the property then I see that the property does have a value.

Can anyone help me out I am kind of loosing my mind because yesterday I did exactly the same thing on a different WS EntitySet and form elements and it worked fined, but now for some reason it is not working...

    JSON Model - It is Client Side Model

    ODATA Model - Server Side Model

    Try ODATA Model instead of JSON Model.

    JsDoc Report - SAP UI development Toolkit for HTML5 - API Reference - sap.ui.model.odata.ODataModel

    For Ex:

    Simple OData Binding with SAPUI5 | SCN
