to call onChange event after pressing Enter key

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 onChange 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.

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
});
