Editable column's value not getting 'persisted' in AdvancedDataGrid
===

I have an AdvancedDataGrid (whose dataProvider is a variable being bound from my main mxml file, not sure if this is relevant to my problem ). I'm setting one of the AdvancedDataGridColumn's editable property as true, and when I click on the cell in the UI, it is infact editable. But when I press enter/move to a different cell, the old value returns and the newly entered value is lost. Would anyone have any ideas why that's happening? Do I have to manually change the variable provided in the dataProvider?...I would think that would happen automatically right? I'd appreciate any help! 

Thanks.
