In container-grid, selected cell data is not getting updated if there are 2 different grids but sharing single method to update

[Ankita2005199]

Here is stackblitz url
Editor url : https://stackblitz.com/edit/ngx-drag-to-select-mcmmtg?file=src/app/app.component.html
Application url : https://ngx-drag-to-select-mcmmtg.stackblitz.io

suppose we select Document1 cell from First container-grid then in selectedIds section [ 1 ] will appear as result, then if we select Document2 cell from second container-grid then in selectedIds section [ 2 ] will appear as result but again if we select Document1 from First container-grid then in selectedIds section [ 1 ] should appear but it will showing second container-grid result.

Note : If we select cell again which was previously selected in container-grid then selection is getting ignored , if we select another cell for this grid then it is working fine.

Expected result : cell should be selected again and result should get updated
