Grid's ChangeLog is not capturing all modifications

[maw]

I am evaluating Complete UI to bring into a project.
As part of this, I was looking at the change log that is part of the
Grid component.
What I noticed is that not all changes were being put into the
ChangeLog.
Has anyone else seen this issue?

To re-create the issue, start with any Grid component, I chose the
example index.html from the zip file, under:
samples-client-grid-html-basic.

After the Grid, i added the following button:
<button onClick="sendGridData('SimpleGrid')">sendGridData</button>

which calls the following javascript to view the change log

function sendGridData(myGridID)
{
alert( nitobi.getComponent(myGridID).getDataSource().getChangeLogXmlDoc
().xml );
}

I noticed some of the changes were there, but not all of the changes.
I was modifying the first 4 rows, changing the Name values to A, B, C,
D respectively.

If anyone can comment on this, that would be great.
Thanks.
