I'm using text.js to load templates and I'm getting an error on
require('text!templates/categories.html')
the error is
Uncaught Error: Module name "text!templates/categories.html_unnormalized2" has not been loaded yet for context: 
Have a look at my view section in the require loading process of the template that's where the error is thrown.
Project directory structure:
js
    /app
        ....
        views/categories
        templates/categories
    /lib
        /jquery
        /underscore
        /backbone
        /text
    /vendor
        /jquery-ui
        /fancytree
