client side templating for jquery mobile

Need some interactive templates using EJS (embedded javascript) implemented for use with jquery mobile and to interact with a custom backbone collection and models. [A sample environment to develop the templates will be provided and you can have a look here][1] Please read the details of the job below. ## Deliverables We are looking for a complete interactive implementation of a Loyalty type system where a end user does an action N number of times to unlock a reward, ie buy 10 get 1 free type scenario Data can be stored within the model and retrieved later on. Restrictions will be placed upon a few factors, ie location (use geo api from phonegap), time since last claim (ie might be 24 hours) and use of a scanned qr code (assume it's a async function) and/or button to claim scanqrcode(callback success, callback failure) success callback will be given the data from the scanned qr code, the fail callback will simply be called. This is for use in a mobile application, templates are stored in the database hence all code has to working inside the environment given, including interactions with the end user.
