When I try to use {{did-insert this.initialiseCategory}}, in my initialiseCategory function (which does get called) there is no “this”… it’s undefined. Any ideas?

 initialiseCategory() {
alert("test " + this); // 'this' is undefined
this.category.categoryIsOpen = true; // can't call category of undefined

}

<li {{did-insert this.initialiseCategory}}>
<a href="#" class="category-caption" {{on "click" this.toggleCategory}}><span>{{this.title}}</span>
     <span class="expand-icon">
      {{#if this.categoryIsOpen}}
        <img src="{{root-url}}/down.png"/>
      {{else}}
        <img src="{{root-url}}/up.png"/>
      {{/if}}
  </span>
</a>
