Protractor find element inside parent - angularjs

Question

I have a protractor test where I create a user and it is then added into a table of users. I then want to find the user that was created and click the edit/delete buttons. The user could be in any of the rows so I don't want to hardcode the test to a specific row just in case it's not in the specified row.
html
<tr ng-repeat="user in users | orderBy:sortType:sortReverse | filter:query track by $index">
<td class="text-center" title="{{$index + 1}}"><span class="section-index" id="index">{{$index + 1}}</span></td>
<td title="{{user.username}}">{{user.username}}</td>
<td title="{{user.email}}">{{user.email}}</td>
<td title="Role">
<span class="label" ng-class="{'admin': user.role.name == 'ROLE_ADMIN',
'user': user.role.name == 'ROLE_USER', 'trainer': user.role.name == 'ROLE_TRAINER',
'reviewer': user.role.name == 'ROLE_REVIEWER'}">
{{user.role.name | roleFilter: true}}
</span>
</td>
<td title="Created">{{user.creationDate | date:"dd MMM yyyy"}}</td>
<td class="text-center" title="Edit">
<span class="btn-details standard pull-right" ng-click="editUserClicked(user.id)">Edit</span>
</td>
<td title="Delete">
<span class="btn-details warning pull-right" ng-click="deleteUserClicked(user)">Delete</span>
</td>
</tr>
user-spec.js
var editedUserCell = element(by.css('td[title="' + EDITED_EMAIL + '"]')).getWebElement();
var deleteButton = editedUserCell.getDriver().findElement(by.css('[ng-click="deleteUserClicked(user)"]'));
Using the example from http://www.protractortest.org/#/api?view=webdriver.WebElement.prototype.getDriver, it finds the first button on the page and not the one inside the parent, can anyone help?
