Empty string assignment via falsy value

[volegg]

If we have boolean value in data provider all False value will be empty string ''. It is unexpected behaviour. Should be fixed something below (index.js):

var originValue = item[field];
tmpValue = originValue === undefined || originValue === null ? '' : originValue;
