How to use setState inside handsontable functions

Getting help Questions
1

Hi team,

how do we change state of react component inside handsontable functions? for example, I would like to change state in following example-

afterCreateRow: function(index, amount){
let newArr = [];
newArr.push(amount);
this.setState( {updatedArray: newArr} );

      }

but this is not instance of react component and i cannot call setState(). how do i call setState() here?

Hey @rohit.parwal

I just got a hint that you should replace afterCreateRow: function () {} with afterCreateRow() {} or use the arrow function afterCreateRow: () => {} then you’ll 90% sure that this is the component.
You can also define var self = this; and use it within the self.setState() function.

thanks,
if I use the arrow function afterCreateRow: () => {} then i would get react component instance. But in this case, how do i get instance of handsontable?
