将参数传递给视图，然后传递给Ember.js中的帮助器

Question

I have 2 views that share a view and I am trying to pass variables between them to turn on|off various html segments. Is this possible? When I run console.log the view.showTitle variable = "view.showTitle" not 1 like it should be? Odd, right?

view 1 calls view 2 and passes param:

{{view "components/social" showTitle="1"}}

view 2 tries to pass this param to a helper function:

{{#variable-exists view.showTitle}}
  YES
{{else}}
  NO
{{/variable-exists}}

the helper being called:

export default function(elem,options) {
  if (Ember.isEmpty(elem)) {
    return options.inverse(this);
  } else {
    return options.fn(this);
  }
}

I am using the ember cli project to build my ember application.

Following these 2 guides a-way-to-let-users-define-custom-made-bound-if-statements and custom bound helpers I was able to adjust my shared views to use this instead of the standard #if statement. This should be more secure than just tossing an #if in there.

<li>
    <a href="{{unbound view.varProductSocialBlog}}">
        {{#if-equal view.showDiv "true"}}<div>{{/if-equal}}<i class="fa fa-rss-square"></i>{{#if-equal view.showDiv "true"}}</div>{{/if-equal}}
        {{#if-equal view.showTitle "true"}}Blog{{/if-equal}}
    </a>
</li>
