update table action buttons after ajax finished

[Cindy Lu]

Scenario:
Volume Quota is set to 3. Create 3 volumes on Projects > Volumes. 'Create Volume' button is now disabled and reads 'Create Volume (Quota Exceeded)'. When you delete it, it isn't immediately deleted, rather it uses ajax polling to determine the state. The button still reads 'Create Volume (Quota Exceeded)'. User needs to do a manual refresh to see the table actions get updated.

Same goes for Delete. If you delete all volumes, the 'Delete Volume' button should also be removed. However, it doesn't get removed until you refresh the page.

We fixed this bug by adding 'btn-create' class to CreateVolume action. And when deletion finished, row update action will change the status of create button "btn-create" simultaneously.

    Add "btn-create" Class to Create Volume Button

    Create volume button doesn't have 'btn-create' class. So when
    volume quota exceeded, and then delete volume, create volume
    button will not come back to enabled automatically, because
    that will not run the update action.
