Hello. I am using a custom column editor as shown in your example : https://docs.telerik.com/kendo-ui/knowledge-base/custom-editor-autocomplete. Even in the example that you provided, if I type a value that is not in the list, on focus out the field will display "undefined" and will remain this way even if i try to select another value. Is there a fix for this situation? Thank you in advance :)
I attached a screenshot from your working example.
