Polymer Get Data Binding From User Without Using Node.Bind

With polymer you can create some interesting things going through the tutorial they offer on the website it creates like a portfolio type listing of user is there a way to add to the list from the web? So basically have a forum? My problem is you can do this with Node.Bind as you can see here, but my web hosting doesn't allow me to use node.js so how would I get around this? Could I use javascript or jquery? I have looked into the data binding information from the website but couldn't find anything that was helpful. If someone could point me in the right direction that would be nice.
