I'm working on a SAPUI5 Master Detail application with Odata model Two Way Binding. When I click on a header element and enter data for its items and click submit, the entered data is still there. Even if I click on another Header element, if I go back to the previous header element its data is still there. I want the entire model to be completely refreshed on every click on a header element. I tried SubmitChanges method, but it's not working ...
