Filtered datasource for ajax?

[mke21]

Hi,

Thank you for this package. It is very usefull.
I have one problem, though. In the examples, there is a clear example how to get customised source data for ajax by using FeedDataView, but it seems like this only works if you have a fixed value on which to filter (like '.filter(id__gt=5)' in the example). How could I make this more flexible, so I can change the value 5 on runtime?
