Relation Types Umbraco

[VanilsonWDD]

Hi Devs, I´m trying to implement relations between nodes using Umbraco Relation Editor, in the backoffice I can see the relation that I have created, but I'm having problems when I try to get the values.

Code
@foreach (var item in Model.Content.Related<IPublishedContent>("relationType")) { <p> @item .Name </p> }
When I run the project it doesn't show me any values.

I´m using Umbraco 7.2.1 and Umbraco Relation Editor 1.1.5550

Best regards
