the important part underscore template not working. saying '_' on line: _.each(items, function(item) undefined. why happening? tried moving underscore script include top of page , didn't help.

i unable reproduce "_ not defined" issue, did find issue may running into: you're referencing items variable items, never told _.template want data in items. use object literal data:

_.template($('#skillstemplate').html(), {     items: [{ name:"linux", value:"test" }] })

(also, you're using item.get('name') when data plain object rather underscore model, assume remnant original code after simplified code question.)
