When a date is selected in the Grid and the value is cleared using the filter method, the filterMenu keeps the value of the Date fields.
The Grid is filtered and the filter is cleared correctly, but the value of the date remains in the filter menu.
When the Grid filter is cleared, the value of all inputs in the filter menu should be cleared as well.
$('.k-filter-menu-container [data-role="datepicker"]').data('kendoDatePicker').value(null)
