Do you have jsonP endpoint which automatically converts and sends the jsonp object to the user. if jsonP you should get straightway.

If it is not jsonp end point , change your backend to a well formated string which is of jsonP notation and do a eval at the UI.

You will have some cross browsers issues also.follow the below link

Custom jsonp binding

<endpoint address="ajax" binding="customBinding" bindingConfiguration="jsonpBinding" behaviorConfiguration="JsonBehavior" contract="InterfaceGoeshere"/>
