I have a similar scenario that I don't know if it is supported.
I have a kendo datasource with one field, let's say tags, that can have, or not, any tags data.
In the case that the model has no tags I want to display something like "no tags".
What I have done for now as workaround is having an extra method in the datasource model definition that is a function like
Which is very dirty, besides the fact that 'this' has different values depending if I am binding the list or a selected item.
I tried to externalize the method to a separate module and have something like:
but this doesn't work, i get ther error "Mozilla error: invalid scope variables"
Is this supported?
