kendoGridFilterCellTemplate not working in custom wrapper in angular 7

I have an angular component which displays a kendo grid from a wrapper,
custom filter templates is not working through the wrapper:

My Component:

                <system-grid [ApiUrl]="'Some/Random/Api'" [Filterable]="'menu'">
                    <kendo-grid-column field="Country" title="Country">
                        <ng-template kendoGridFilterCellTemplate let-filter let-column="column">
                            <kendo-grid-string-filter-cell [column]="column" [filter]="filter" operator="startswith">
                                <kendo-filter-startswith-operator></kendo-filter-startswith-operator>
                                <kendo-filter-eq-operator></kendo-filter-eq-operator>
                            </kendo-grid-string-filter-cell>
                        </ng-template>
                    </kendo-grid-column>
                    <kendo-grid-column field="Sex" title="Gender" width="150"></kendo-grid-column>
                    <kendo-grid-column field="Active" title="Active" width="150" filter="SystemBooleanFilterComponent">
                        <ng-template kendoGridCellTemplate let-dataItem let-rowIndex="rowIndex">
                            {{dataItem.Active?'Yes':'No'}}
                        </ng-template>
                        <ng-template kendoGridFilterCellTemplate let-filter>
                            <system-boolean-filter [field]="column.field"
                                                   [filter]="filter"
                                                   [filterService]="filterService">
                            </system-boolean-filter>
                        </ng-template>
                    </kendo-grid-column>
                </system-grid>

Now the kendoGridFilterCellTemplate seems to work just fine but the directive kendoGridFilterCellTemplate is not working through my wrapper for grid named system-grid

That is it that i’m doing wrong ?
