Hitting "Update" fires "create"

[CS]

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"?

[CS]

To get more specific, I have values of null in the table, so the property exists but not the value. When I change the value a "create" is fired since the value did not exist before but actually it should only update the null value to the current. If a value was set before "update" is fired. I only want to fire an "create" if one special cell is filled and "update" otherwise.

Hi Stefan,

This behavior could be observed in case the Model's ID is not specified. Basically, the DataSource checks the ID of the item being edited, and if it is different than 0 (or the default value of the ID field) then Update is called, otherwise - Create.
