Issue regarding multiple dxhtml gantt charts

I am using the commercial version of DHTMLX Gantt.
I am using Gantt at 2 places in my angular application and both the places have data processor attached.
Now When I update any task from one places it calls update function at both the places. Can you suggest a way to detach the data processor when navigating from one place to another?

Please, don’t post same questions in different places.
