Description of problem:

On RHEVM admin web, why can't i sort by column heading? For example clicking on "host" would sort all VM's per running host (ordered in abc). Clicking on uptime would resort VMs with longest run time on top, another click on same column heading would resort in revers order shortest time first, and so on for other columns as well.

Often find my self clicking (again and again) on column heading to sort without effect. 


Filtering on search bar isn't the same. 
Version-Release number of selected component (if applicable):
3.3.1-0.48.el6ev

How reproducible:


Steps to Reproduce:
1. Login to admin GUI
2. Under VM tab, click on column heading 
3.

Actual results:
Nothing happens

Expected results:
I wish it would sort by that column.
