I use yours gantt wrapper, but I have problem with refresh or change datasource when some event happened. I check reactive changes at others wrapers i.e. grid and ther this is working fine. I try also manipulate yours exemples at sandbox and plnkr, but it always fails.
I'd do something like that.
How can i do this? I found some post and then was admin anserw that vue-wrappers from wersion 2018.2.xxx are reactived. I will be greatfull for working plnkr.
