[flexcoders] Help! - AdvancedDataGrid - Applying sort as if user clicked column header

[InvertedSpear]

Check out the advancedDataGrid below in the ***s. After I group I loose the
sorting I applied to the dataprovider, and no matter what I try or when I
try it, sorting the dataprovider has no effect. But the user can sort by
clicking on a column header. So I want to simulate that click in a function
but I am having no success.

I'm trying this code in the ///s and calling it after I refresh the grouping
collection. I know this code isn't breaking with any sort of error cause the
Alert.show I fire right after it works fine. Anyone know what I'm doing
wrong?

////////////////////////////////////////////////////////
gridTemplates.dispatchEvent(
    new AdvancedDataGridEvent(
        AdvancedDataGridEvent.HEADER_RELEASE,
        false,
        false,
        0
    )
);

Here's the AdvancedDataGrid:
