How to add feature attribute value

KK2014 — Fri, 20 Mar 2015 13:04:56 GMT

I want to create o point feature and add string value to string attribute (ex:"description") in offline status and then sync to server.In my example I can create point feature and I give value to "description" attribute and then I give parameter in addFeature( ).In online mode my new point feature geometry created but my "description" attribute value is empty.How can I record my attribute value(ex:"Hi").?My code is below:

Thanks.
