How to set default Checked in checkbox ReactJS?

Question

I'm having trouble to update the checkbox state after it's assigned with default value checked="checked" in React.

var rCheck = React.createElement('input',
    {
        type: 'checkbox',
        checked: 'checked',
        value: true
    }, 'Check here');

After assigning checked="checked", I cannot interact the checkbox state by clicking to uncheck/check.

To interact with the box you need to update the state for the checkbox once you change it. And to have a default setting you can use defaultChecked.

An example:

<input type="checkbox" defaultChecked={this.state.chkbox} onChange={this.handleChangeChk} />
