Description of problem:
In Group View
When the translation is updated, click the locale under Languages column should update the stat of that locale, however, it did not.

Version-Release number of selected component (if applicable):
Zanata 3.3.0-SNAPSHOT (20140217-1515)

How reproducible:
Always

Step to reproduce:
1. You need two browser tabs. One showing the group view, the other is in translation editor view, editing one of the documents that belong to project in the group.
2. In translation editor tab, 
   Add a new translation or remove translation to make statistic change.
3. In group view tab, 
   switch the sort under both column "Languages" and <LOCALE> Projects to "word remaining" so you can easily compare.
4. Click at the <Locale> you were editing under the column "Languages" to get the statist of that locale

Actual:
The words under languages column does not equal to the sum of the project remaining words.

Expected:
The words under languages column should equal to the sum of the project remaining words.

Additional:
The value will be corrected after reload the page.
