Highlighting not working properly when setting value of textarea using jquery

[smita-chougale]

I have textarea as follows and highlighted word using highlightTextarea:

$('textarea').highlightTextarea({
     words: ['brand']
})

When I try to set the value of textarea using jquery:

$('textarea').val('changed_value == 9')

again called following method :

$('textarea').highlightTextarea({
     words: ['brand']
})

then output is as follows:

It is not reseting the mark tag.
Only after I try to edit the textarea value by typing, it removes the highlighted mark from background.

You can use it dynamicly first need to destroy
$('#textarea').highlightTextarea('destroy');
and then reuse it.
$('textarea').val('changed_value == 9')
$('textarea').highlightTextarea({ words: ['brand'] })
