Html Spell Check not working properly in IE11

Hi,

I have implemented spell checker of html5 using spellcheck="true" attribute and its working in IE when er type the text, but if we refresh the page and come back and focus on the text area the spell check is not done unless i press space in IE 11. other browsers are working fine. is there a alternative or is this the default behavior of IE 11 with this attribute?

Please respond, Thank You.
