.net dataset.haschanges is incorrectly false

See more:

C#

Addresses table has two rows. If first row is modified, HasChanges function is working as expected.
If second is modified, HasChanges function is not working as expected.
Please let me know how to rectify this. Thanks in advance.

DataTable dt = data.Tables["Addresses"];
     this.BindingContext[dt].EndCurrentEdit();
             
     if (! data.HasChanges(DataRowState.Modified))
	return false;

What I have tried:

after keeping below lines, it started recognizing first row changes.

DataTable dt = data.Tables["Addresses"];
     this.BindingContext[dt].EndCurrentEdit();
