ODataModel error: Invalid metadata document (Initial loading of metadata failed)

As suggest in the comments, the problem is the OData version. I've fixed the issue using sap.ui.model.odata.v4.ODataModel. In the fourth version of OData, the right way to perform CRUD requests is by using bindings. I've found this official tutorial very useful in order to understand how they work.
