A helper named 'ember-chosen' could not be found

[rcrenshaw84]

I ran the command "ember install:addon ember-cli-chosen" and it seemed to install correctly.
I added the following code to a template
{{#ember-chosen multiple=true value=model.agencyRole class='form-control' id='agency-role-field'}}
Select Agency Roles
{{#each agencyRoleList as |agencyRole|}}
<option {{bind-attr value=agencyRole.code}}>{{agencyRole.name}}
{{/each}}
{{/ember-chosen}}

When I try to go to that page, it is blank and I get the error "ember.debug.js:16591 Uncaught Error: Assertion Failed: A helper named 'ember-chosen' could not be found" in the console.
