Accessing MetaData in SAPUI5

Hello

I would like to access the texts from the ABAP dictionary and use them as labels on the UI5 controls, I have tried using the getServiceMetadata function of the oData model,but i was unable to convert to JSON model which i can used further.

I have followed following thread

http://scn.sap.com/thread/3385666

Can anyone guide me to convert it to JSON model.

Thanks and Regards.
