Error: sort-by is not a helper

[syedasadhasan]

When implementing paper-data-table I am getting this error "sort-by is not a helper". What wrong I am doing?

[ibarrick]

sort-by comes from ember-composable-helpers. It was used in the demo application just to illustrate the use of the sort prop.

As the maintainer mentioned, @bloodknight2010, you need the ember-composable-helpers addon. You can get it with ember install ember-composable-helpers.
