We are not using this style of angular any more, moving to components (directives), with controllers that are bound in specific way (so no scope hierarchy)

So do something like this:

this.publishAppEvent('show-modal', {
  templateHtml: '<data-export-modal data-list="dataList"></data-export-modal>',
  scope: { dataList: this.dataList  }
}); 

And then define a new data-export-modal component, use this for reference:
https://github.com/grafana/grafana/blob/master/public/app/core/components/help/help.ts
new to add the scope: {dataList: "="} binding to the directive declaration

Thanks for the review. Update follows

[cederigo]

I renamed it to export-data-modal because the prefix "data-" is stripped away during the directive name normalization: See: https://docs.angularjs.org/guide/directive#normalization

Same for the attribute "data". The attribute "data-list" would resolve to "list" in the directive..

[cederigo]

Ok like this? cheers

Thanks for fixing this! Sorry about the delay - we have been busy with the new Grafana release during the last week or so.

Merged the two commits manually.
