Need help in Getting Access of Collection Helper Methods on DDP


i am working on Meteor app (build in 1.3.5) which is connected to our iOS app through DDP and its connected and i am able to get request and sockets working on it on iOS

but i am facing issue in sharing access of helper methods which exists in my collection … does anyone know how could i share collection model and its helper methods on DDP ?
