Can we add additional method `getTemplate` and rewrite this code so:
```javascript
getTemplate: function (templateName) {
  return this.TEMPLATES[templateName] || '';
},
refreshCatch: function (args) {
  ...
  if (self.options.showPublicPrivate) {
     var templateName = this.options.instructor_username ? 
          "annotationPublicPrivateInstructor" : 
          "annotationPublicPrivate";
  }
  
  el.html(self.TEMPLATES.annotationList({ 
    ...
    PublicPrivate: this.getTemplate(templateName),
    ...
  }
  ...
}
```
