emberjs input checkValidity and setCustomValidity

Is there a way to use checkValidity() setCustomValidity() within ember? For example, in my controller upon submission I have:

var inpObj = this.get('name');
if (inpObj.checkValidity() == false) {
    alert('ok');
}

and of course this is my handlebar code:

{{input id="name" type="text" value=name placeholder="Your Name" required="true"}}

Upon submission of this, I get this error message:

inpObj.checkValidity is not a function
