### What was done
* In the method `_raiseCellClickEvent` created a fallback using the
`binding` instead of getting the column that is `undefined` in this
scenario.

### Test Steps
1. Go to a screen containing an autogenerated Grid using JSON Serialize.
2. Click any cell with the dev tools console opened
3. Checked that no error is thrown


### Checklist
* [X] tested locally
* [X] documented the code
* [X] clean all warnings and errors of eslint
* [ ] requires changes in OutSystems (if so, provide a module with
changes)
* [ ] requires new sample page in OutSystems (if so, provide a module
with changes)
