Will this work if I am trying it in JS bin? I changed the dependencies so it uses the links that jsbin needs. But the output just kind of displays the top of some box.... and did I mention I'm new to handlebars?
Thanks for this. It allowed me to see that in order to use handlebars you must still include underscore. I'm not sure why that is but I had assumed you swopped out underscore when using handlebar and all sorts of pain resulted.
Thanks a lot. This example really helped me!
FYI - I had to update the following line as per the other post at https://gist.github.com/4682984
I had to change this.$el.html(html);
to $(this.el).html(html);

there's a typo, instead of personView.el = $('#personConatiner')
should be: personView.$el = $('#personContainer')
same for the peopleView.$el
I am using the latest versions, jQuery 2.0, Backbone 1.01 etc
