The store reader expects an array of items, as i see you are sending just one record.
so instead of : {"indoor":false,"kad_name":"filename"..} you should send an array and a root object. Something like:

{"values":[{"indoor":false,"kad_name":"filename"..}]} and then just add root “values” to the jsonreader. Default root is “” so you can send it with default blank.
