I am trying to do a custom listview for my products.

Each product has a checkbox list of multiple choice so the value of the property is an array, for example: ["521","527"]

In my listview I want to display a list of values (text) instead of numbers, eg. "shirt, sleeve".

So far I have added a function in my angular controller but I'm getting an empty array as a result.

I followed the documentation https://our.umbraco.org/apidocs/ui/#/api/umbraco.resources.entityResource and wrote my function:

function getTypes(item) {
        entityResource.getByIds(item.types, "DataType")
            .then(function (entity) {
                item.typeList = entity;
            });

item.types passes a correct value as ["521","527"] while item.typeList displays an empty list [] as a result

Not sure how to display correct values in this case?

I'm using Umbraco 7.5.14
