Answer 1

I faced the same issue but able to resolve this issue. Below code is for enter text in input field and fire onchange event.

WebElement textBox = driver.findElement(By.xpath(xpath));
textBox.sendKeys("Test");
((JavascriptExecutor) driver).executeScript("arguments[0].onchange", 
  Arrays.asList(textBox));

Hope it will work!

Answer 2

I had a similar problem, with a Dropdown list made with Ajax.
As the user types in a field, the system displays AJAX divw with several options, each one as a link with target='#'

And even worse, there was a function called on the onChange() that filled a system flag, and that flag would be used as a validation on the form.submit() (oh, the pain)

Anyways, my solution for this:
1 - Selenium sendKeys command so the Ajax div would appear

<tr>
    <td>sendKeys</td>
    <td>id=txtTipoDocumento</td>
    <td>ipsum lorem</td>
</tr>

2 - wait for the link with the expected option to appear

<tr>
    <td>waitForElementPresent</td>
    <td>link=ipsum lorem</td>
    <td></td>
</tr>

3 - selenium clickAt the link

<tr>
    <td>clickAt</td>
    <td>link=ipsum lorem</td>
    <td>10,20</td>
</tr>

4 - Here is the ONE of the catches: manually fire the onChange() AND blur events. Also, foce the browser to set focus on different field

 <tr>
        <td>fireEvent</td>
        <td>id=txtTipoDocumento</td>
        <td>blur</td>
    </tr>
    <tr>
        <td>fireEvent</td>
        <td>id=selSerie</td>
        <td>change()</td>
    </tr>
    <tr>
        <td>fireEvent</td>
        <td>id=selSerie</td>
        <td>blur</td>
    </tr>
    <tr>
        <td>focus</td>
        <td>id=imgDataElaboracao</td>
        <td></td>
    </tr>

5 - Finally, to be sure, I made Selenium do execute the ClickAt() command on the Submit button of the forme, between a mouseDown and MouseUp commands

<tr>
    <td>mouseDown</td>
    <td>id=btnSalvar</td>
    <td></td>
</tr>
<tr>
    <td>focus</td>
    <td>id=btnSalvar</td>
    <td></td>
</tr>
<tr>
    <td>clickAt</td>
    <td>id=btnSalvar</td>
    <td>10,20</td>
</tr>

Not elegant, but it worked.
