具有特殊字符的angularjs表达式

Question

Some angular expressions contain special characters (eg '-'):

<tr data-ng-repeat="asset in assets">
  <td>{{asset.id}}</td>
  <td>{{asset.display-name}}</td>
  <td>{{asset.dns-name}}</td>
  <td>{{asset.link[0].uri}}</td>
</tr>

In above code: {{asset.display-name}} and {{asset.dns-name}} prints 0 which is not correct. How to escape part of an expressions?
