or how to use functions in templates without filters. FcName ({{I}}) function name, which is not feasible to write in the template. I don't know what to do with the data in the template.

now that you know how to use the filter, add var defaults = require ('art-template/lib/defaults') to the app.js;
in this case template.defaults.imports.transNumber = function (number) {

return "";

}

you can use < td > {{I | transNumber}} < / td >

directly in the template.
