Checkbox is not getting updated in React JS Functional component

I'm trying to add a checkbox in react js but it is not changing its value.

function TestToolbar(args) {
  let overRideFlag=0;
  if (overRideFlag === 0){
    overRideFlag=false;
  }
  else{
    overRideFlag=true;
  }
  const handleOverRideChanges = (overRideFlagParm) => {
    overRideFlag=!overRideFlagParm;
  };
  return (
    <div className="">
  <Col sm={1}>
  <div className="" onClick={() => handleOverRideChanges(!overRideFlag)}>
        <input type="checkbox" id="overRideEnabled" name="override" checked={overRideFlag} onChange={() => handleOverRideChanges(overRideFlag)} />
        <label htmlFor="overrid">Override</label>
  </div>
  </Col>
  <Col sm={9}>
    <AddAnotherComponent disabled={disabled} overRideStatus={overRideFlag} />
}
);
}

The issue is that the value of overRideFlag is always true. it is not changing to false at no time. Another issue is checkbox is not getting checked even though its value is true. Finally am passing the value to another component as a prop but it is not getting change. Could anyone kindly advise how the issue can be resolved.

#UPDATE

When I click the checkbox actually the handleOverRide Changed execute twice
