clicking inner div to trigger outer div event

I have a React functional component that returns a div containing child divs. It comprises an Item, and is used by another component to populate a list of Item rows. That list component gives each item an onClick event function, which I've placed on the outer div of each Item:

import React from 'react';

const Item = props => {
  const { itemid, data, onClick } = props;
  
  return (
    <div itemid={itemid} type="button" tabIndex={0} onKeyPress={onClick} role="button" onClick={onClick}>
      <div>
        {itemid}
      </div>
      <div>
        {data}
      </div>
    </div>
  )
}

export default Item;

My thought is each entire Item row (both inner divs), when clicked, should trigger the onClick event attached to the outer div. But nope - the inner divs above do not apparently inherit the onClick event from the outer div.

The onClick event is only triggered by the inner divs if I attach it to them directly.

Is there some way to have the inner divs inherit the onClick attached to the outer div?

As it turns out, this seems to solve my problem:

import React from 'react';

const Item = props => {
  const { itemid, data, onClick } = props;
  
  return (
    <div itemid={itemid} type="button" tabIndex={0} onKeyPress={onClick} role="button" onClick={onClick}>
      <div style={{ pointerEvents: 'none' }}>
        {itemid}
      </div>
      <div style={{ pointerEvents: 'none' }}>
        {data}
      </div>
    </div>
  )
}

export default Item;

I guess the pointerEvents: 'none' keeps the child divs from being clickable, so the outer div then takes the click.

Still hoping for a better solution, as this seems a little strange.

As suggested by @DucHong e.stopPropagation() will prevent the parent element clicks if you put it in the click event of the child element.

        import React, { useState } from "react";
        import './RowForm.css';
        import { BsFillCheckSquareFill } from "react-icons/bs"
        import { BookmarkTransaction, ChangeFormData, ClearTransaction } from "../../Accounts/Store/accountsSlice";

       ...
       ...
       ...

        <tr
            key={id}
            onClick={(e) => {
                dispatch(ChangeFormData({
                    isChecked: true,
                    formData: getValues()
                }))
            }}
        >
            <th className="checkbox-th">
                <FormGroup check className="mt-2">
                    {isChecked ?
                        <BsFillCheckSquareFill
                            onClick={(e) => {
                                e.stopPropagation()
                                dispatch(ChangeFormData({
                                    isChecked: false,
                                    formData: getValues()
                                }))
                            }}
                            className='check-icon'
                        />
                        :
                        <div
                            onClick={(e) => {
                                console.log("===>true bottom")
                                e.stopPropagation()
                                dispatch(ChangeFormData({
                                    isChecked: true,
                                    formData: getValues()
                                }))
                            }}
                            className='checkbox-wrapper'
                        />
                    }
                </FormGroup>
            </th>
       </tr>
