Odag-binding strange behavior

[bbongagus]

Hello guys, i have template and main app:

in template i have following code:

SET ns = '';
OdagBindingCityName:
LOAD * INLINE [
VAL
$(odo_city_name)[1]{"quote": "", "delimiter": ""}
];
CALL BuildValueList('ns', 'OdagBindingCityName', 'VAL', 39);

When i select field "city_name" in main_app i see next thing: 

12

What could be the problem?
