title: to call onChange event after pressing Enter key
body: <p>I am new to Bootstrap and stuck with this problem. I have an input field and as soon as I enter just one digit, the function from <code>onChange</code> is called, but I want it to be called when I push 'Enter when the whole number has been entered. The same problem for the validation function - it calls too soon.</p>
  
  <pre><code>var inputProcent = React.CreateElement(bootstrap.Input, {type: "text",
    //bsStyle: this.validationInputFactor(),
    placeholder: this.initialFactor,
    className: "input-block-level",
    onChange: this.handleInput,
    block: true,
    addonBefore: '%',
    ref:'input',
    hasFeedback: true
  });
  </code></pre>
