Handle Change of FormControl React
<p>Hey so I have a text box/FormControl that's supposed to update a field in a json in this.state. I was wondering if there was a better way to do onChange?</p>

<pre><code>&lt;FormControl 
  type='text' 
  placeholder='enter' 
  defaultValue={this.state.form.name}
  onChange={this.handleChange.bind(this, 'name')}
/&gt;
&lt;/FormGroup&gt;
</code></pre>

<p>`</p>

<pre><code>handleChange(change, event) {
    var toChange = this.state.form;
    toChange[change] = event.target.value;
    this.setState({form: toChange});
  }
</code></pre>
