In my render method I have something like

```
<input type={dynamicTypeValue} value={dynamicValue} />
```

If I first render this input as a number, (e.g. `dynamicTypeValue = 'number'; dynamicValue = 5`) but then change the input to a string: (`dynamicTypeValue = 'string'; dynamicValue = '01/01/2016'`) I get a warning 
that the new value is not a valid number:

```
The specified value "01/01/2000" is not a valid number. The value must match to the following regular expression: -?(\d+|\d+\.\d+|\.\d+)([eE][-+]?\d+)?
DOMPropertyOperations.js:142 The specified value "01/01/2012" is not a valid number. The value must match to the following regular expression: -?(\d+|\d+\.\d+|\.\d+)([eE][-+]?\d+)?
```

Is this expected behavior?

it('should throw if both checked and checkedLink are provided', function() {
    var node = document.createElement('div');
    var link = new ReactLink(true, jest.fn());
    var instance = <input type="checkbox" checkedLink={link} />;
    expect(() => ReactDOM.render(instance, node)).not.toThrow();
    instance =
      <input
        type="checkbox"
        checkedLink={link}
        checked="false"
        onChange={emptyFunction}
      />;
    expect(() => ReactDOM.render(instance, node)).toThrow();
    instance =
      <input type="checkbox" checkedLink={link} onChange={emptyFunction} />;
    expect(() => ReactDOM.render(instance, node)).toThrow();
  });
  it('should update defaultValue to empty string', function() {
    var container = document.createElement('div');
    ReactDOM.render(<input type="text" defaultValue={'foo'} />, container);
    ReactDOM.render(<input type="text" defaultValue={''} />, container);
    expect(container.firstChild.defaultValue).toBe('');
  });
  it('should throw if both checkedLink and valueLink are provided', function() {
    var node = document.createElement('div');
    var link = new ReactLink(true, jest.fn());
    var instance = <input type="checkbox" checkedLink={link} />;
    expect(() => ReactDOM.render(instance, node)).not.toThrow();
    instance = <input type="checkbox" valueLink={link} />;
    expect(() => ReactDOM.render(instance, node)).not.toThrow();
