    {this.generateColumn(this.props.arrayHeader)}
</wjGrid.FlexGrid>



 generateColumn = (params) => {
    let arrayColumn = [];
        // create column header base on each item
        for (let i = 0; i < paramslength; i++) {
            resultColumn.push(<wjGrid.FlexGridColumn
                key={i+4} 
                header={}
                name={ }
                binding={'' + i}
                minWidth={160} width="*">
            </wjGrid.FlexGridColumn>)
        }
    }
    return arrayColumn;
}

/**
 * initialize grid
 * @param {wijmo grid} grid 
 */
export function initializeGrid(grid) {

    grid.rows.defaultSize = 16;
    grid.columnHeaders.rows.defaultSize = 18;
    // add three extra column header rows
    var hr = new wjcGrid.Row();
    grid.columnHeaders.rows.push(hr);
    grid.columnHeaders.rows[0].allowMerging = true;
    grid.columnHeaders.rows[0].align = 'center';
    grid.columnHeaders.rows[1].backgroundColor = '#182e38';
    grid.refresh(true);
}

detail

[Deprecation] Listener added for a synchronous 'DOMNodeInserted' DOM Mutation Event. This event type is deprecated (<URL>) and work is underway to remove it from this browser. Usage of this event listener will cause performance issues today, and represents a risk of future incompatibility. Consider using MutationObserver instead.

I was try render column in FUNCTION initialize setting grid but column is dynamic and grid does not rerender.

I using "@grapecity/wijmo.all": "^5.20202.732".

what can i do to fix it? help me please!
