This is my grid html
<ejs-grid #GridGirls id='GridGirls' [toolbar]='toolbarOptions'
[dataSource]='finalDataSource_girls.data' [allowSorting]="true" [allowPaging]="false"
[allowPdfExport]='true' [allowExcelExport]='true' (toolbarClick)='toolbarClick($event)'
[sortSettings]='sortOptions' [allowResizing]="true"
(queryCellInfo)='onQueryCellInfo($event)'>
<e-columns>
<e-column field='year' headerText='Year' textAlign='Right' width=75
[sortComparer]='sortComparer'></e-column>
<e-column [columns]="girlsColumns" headerText="Girls Percentage">
<ng-template #headerTemplate let-column>
<div>
<span>{{Summary (' + period +')' | translate}}</span>
</div>
</ng-template>
</e-column>
</e-columns>
Initally it loads perfectly, but on a button click, I am trying to update
girlsColumns
values but it doesn't work and gives this error on console. There is no foreign key defined in my columns data
