In Ember js, periodically check if property has a value

In our project, there's sometime a delay for some data to be provided, in the case fileUrl.

What method in Ember can I use to periodically check that a property has been filled with a value. Then when it's filled, stop the periodic check?

JS (Ember):

import Ember from 'ember';

export default Ember.Controller.extend( {
  licences: Ember.A([
    'Asia',
    'EU',
    'USA'
  ]),

  experimentLicence: 'Asia',

  actions: {
    selectLicence(licence) {
      this.set('experimentLicence', licence);
    },

    saveDataset(model) {
      model.set('licence', this.get('experimentLicence'));

      model.save()
        .then(() => {
          this.send('hideModal');

          /**
           * periodically check if file url is ready to be used
           * Then when file url is ready stop the periodic check
           */
          Ember.run.debouce(() => {
            // check if file url is ready
            if (model.get('fileUrl')) {
              this.send('datasetsIsExportedToMendeleyData', model);
            }
          }); 
        })
        .catch(() => {
          console.log('Oops! Something went wrong. We\'ll fix it as soon as possible.');
        });
    },

    cancel() {
      this.send('hideModal');
    },
  }
});
