JavascriptExecutor doesn't work properly with Selenium

I use JavascriptExecutor to input the text. My code snippet is as follows

 private void inputWorkDescription(WebDriver driver, int rawNumber) throws IOException, GeneralSecurityException {
        if (!getWorkDescriptionFromSheets(rawNumber).isEmpty()) {
            WebDriverWait wait = new WebDriverWait(driver, WAITING_PERIOD);
            WebElement workDescription = wait.until(ExpectedConditions.visibilityOfElementLocated(
                    By.cssSelector("span.placeholder-decoration.ProseMirror-widget span")));
            JavascriptExecutor executor = (JavascriptExecutor) driver;
            executor.executeScript("arguments[0].click();", workDescription);          // ---WORKS
            executor.executeScript("arguments[0].value='123456';", workDescription);   // --- DOESN'T WORK
            executor.executeScript("arguments[0].setAttribute('value', '" 
+ getWorkDescriptionFromSheets(rawNumber) + "');", workDescription);   // --- DOESN'T WORK
        }
    }

Unfortunately, it doesn't work properly. I just see that click command performed but no text input.
I tried different options for text input but it doesn't work.

I used wrong css identifier.
