Unable to add value in a textarea on a website through powershell

Hi,

I am automating our web browser task through powershell. I have a text area on a page where we insert our event proc and then click on submit. I am able to add the text value on the text area and it populates on the IE window page as well but when I click confirm it all through powershell it shows error saying, Please enter a value.

However, If a try adding the same event proc on the text area manually and click confirm. it works.

PS Script:

??($obj.Document.getElementsByTagName("textarea") | select -First 1 ).value = "Events(Startup).group=add+=Administrators /g=A645121"
#click on confirm
$conf = $obj.Document.getElementsByTagName("button") | Where-Object {$_.innertext -eq 'Confirm'}
$conf.click()


HTML Element details:

<textarea data-bind="value: CacheDbControlData, valueUpdate: ['afterpaste'], disable: !isSelectedClass('unformatted')"></textarea>

Any help would be really appreciated.
