I have a small table with a counter for manufactured parts.  
 ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/6/c635c01682e15eb8c8e734deacdf66971012d94a.png)  
I want to restart a count on pressing the button. e.g. it is 3 pm when the button is pressed, so the table should refresh / reset to 0 and start counting up again.

For this I want to use a tag history binding that uses now(0) (only poll once) as start date and so the button refreshes or resets the start date of the binding when it is pressed.

Here I am using a boolean count on when a new product is detected as ready.

I made an event for the button, onClick

```auto
system.perspective.sendMessage('refresh')

```

and a message handler called refresh on the table (I was trying with the first row to test)

```auto
self.refreshBinding('props.data[0].Products')

```

But it is not working… is it a syntax problem or is this not the correct method to use for what I want to do?

</div>

Does `props.data[0].Products` itself have a binding ? Or is the binding on `props.data`, or something else ?

Yes, it has a binding! Every row is binded using the same structure but to different tags.  
The picture above of the binding corresponds to `props.data[0]`

Is it `Products` or `Product_count`?

I just changed it to `Product_count` so that it is easier to explain

did you confirm the messages get recieved?

put in a log or print on the message handler and in the transformscript in the binding^^
