Grid spinner hang

[Satwinder Singh]

I have a grid that I've cleaned up and made it as simple as possible. 

1. simple grid with 3 columns defined and add/edit/delete enabled. No datasource added or defined.
2. data is loaded via a Javascript function, that updates the grid's dataSource. 
   
3. The grid shows the data. It is able to load different kinds of data aswell. (data is loaded based on another dropdown for calendar month, that executes the JS function to load data)
4. When I add a new row, the grid just locks up with spinner. No actionBegin or actionComplete is defined/used. 
5. Editing works fine. If the grid is empty or data is not loaded into the grid, add new row works fine. 

Edit:
I've ruled out any primaryKey issue, I tried unique ID values, but the grid locks up. 

if I reload the data (update the dataSource), the grid updates with reloaded data, but spinner is still there and locked up grid. 

tried .refresh() / .endEdit() / args.cancel = true ... and different combinations.
