How to use the liquid-fire/ember-internals.containingElement function in liquid-fire

_transition: function() {
    var versions = get(this, 'versions');
    var transition;
    var firstTime = this.firstTime;
    this.firstTime = false;


    this.notifyContainer('afterChildInsertion', versions);

    transition = get(this, 'transitionMap').transitionFor({
      versions: versions,
      parentElement: Ember.$(containingElement(this)),
      use: get(this, 'use'),
      rules: get(this, 'rules'),
      matchContext: get(this, 'matchContext') || {},
      // Using strings instead of booleans here is an
      // optimization. The constraint system can match them more
      // efficiently, since it treats boolean constraints as generic
      // "match anything truthy/falsy" predicates, whereas string
      // checks are a direct object property lookup.
      firstTime: firstTime ? 'yes' : 'no',
    });

    if (this._runningTransition) {
      this._runningTransition.interrupt();
    }
    this._runningTransition = transition;
