I have very basic grid using remote date from a MS CRM2013 REST endpoint. I currently try to use inline editing. So I have to click on edit to change row data. When I then change data and hit "Update" I expected that the "update" method is fired but instead "create" and I receive the error "Uncaught TypeError: Cannot read property 'call' of undefined" because I don't have "create" yet. So how can I prevent "Update" fire a "create"?
