FIX: Table editing sometimes not working (#50)

We were relying on the `event.target`, and sometimes that target was not the button element with the `table-id` data attribute, but the svg. 

This commit makes a few changes: 

- renames `tableId` to `tableIndex`
- passes the index as part of the attributes to the `generateModal` function
