In the given code if I select the material in the 6th row or the last row then it is showing in that respective row.
If I add any row afer that and select the material, then also it is showing the material in that last row for example it would be 7th row here.
However, if I select the material in 2nd row firstly, then it is showing the material in the 2nd row.
Now comes the devil, if I add a row after 2nd row and a new row has been added at 3rd position. If I select the material in this layer then the material selected or properties related to that will be showed in the nect row which is 4th.
I have attached the screenshots also.
Here is my code

I would be really grateful if someone can help me in this issue.
I try to change the binding of events or calling of row_num. But it doesn't get solved.
