Filter Kendo UI

Hi,

I'm trying to filter my DataSource with logic "and", and I have few conditions

my code is:

 $("#filterable-listview3").data("kendoMobileListView").dataSource.filter({
                        logic: "and",
                        filters: [
                             { field: "assignedTo14", operator: "==", value: ListOfKabats },
                             { field: "dueDate", operator: ">", value: FromDate },
                             { field: "dueDate", operator: "<", value: UntilDate }
                        ]
                    });

and it doesn't work, it works for me when I do the first condition only, or the two others only- but not all the 3 conditions together.

Do you have any idea why?

Thanks,

Shira
