• browser: any

Steps to reproduce

1. Open the following sample
2. Open the browser console
3. Click the quick filter button of the "Order Date" column
4. Select any date from the calendar
5. Click anywhere to lose focus of the filled-in date input / Click the "Close" button

Result

The filtering event is fired on the following occasions:

1. Once the quick filter button of the "Order Date" column is clicked when no filter is applied
2. Twice when selecting a date from the calendar

Expected result

The filtering event to be fired as for the other columns, f.ex. of type 'string'. To be fired only once when selecting a date from the calendar.
