JavaScript sdk date time filter

I downloaded Power BI angular client sample (https://github.com/Azure-Samples/powerbi-angular-client) and try to implement an advanced filter in the hosting application to filter my report by date time.

It didn't work. The server returns this error: Object {message: "Invalid filter definition"}

Below is the code segment for advanced filter:

    static predefinedFilter2 = new pbi.models.AdvancedFilter({
        table: "f_msANA_byRelease_transformed",
        column: "aaValuePeriodStartTime"
    }, "And",
        {
            operator: "GreaterThan",
            value: "2016-06-01"
        }
    );

I tried to change the date time to different format but hit the same error.

Any suggestion is appreciated.
