Problem with IWDBGrid Async refresh

[Comograma]

I see that you are using templates, but I don't know which picture is which. Seems that the first it the wrong one. Is that correct?

I'm not using templates, just using bootstrap 3. And yes, the first image is with version 15.2.6 wich is the incorrect one.

Can you please create a simple test case with 1 form and 1 grid showing this behavior? 

A IWBootstrap form can be configured in many different ways and there is no guarantee that it will match yours

Ok, this was very painfull but here it goes. Has I said, my test case works great with v15.2.0 and since that until v15.2.6, it doesn't work has expected.
There are images, js and css attached.
Obrigado Alexandre ?
