According to your docs:
There is a default event handler for the Data callback of the datasource. This event handler passes a reference to the combobox firing the event that can be resolved by running ".data("kendoComboBox")" against it.
However if I manually hookup the same function, I get an error when typing something into the combox, because the "selector" parameter isn't actually a combobox.
It appears to be a bug?
I am trying to create a Data function that sends a reference to the combobox calling it as a parameter. And I cannot use strict ID selectors, because all my comboboxes have ID's that are generated dynamically at runtime.
