Bug report

The server filtering is not working for MultiColumnComboBox defined using a tag helper.

Reason: The initialization script returns:
..... kendo.ui.ComboBox.requestData(.....
instead of
..... kendo.ui.MultiColumnComboBox.requestData(.....

Reproduction of the problem

For reproduction details please refer to ticket: #1435798

Current behavior

The server filtering is not working and the server returns all items from the DataSource.

Expected/desired behavior

The server should filter the response based on the data coming from the view.
