You can use this or getElementById function as you used. but you were missing ) syntax in calling function.

<input type="radio" id="radio" value="" name="packages" onclick="callrest(document.getElementById('radio'))"/>

Use this attribute to get value of the radio button

<input type="radio" id="radio" name="packages" onclick="callrest(this.value);"/>

Use like this here 'this' refer to current element :

 <input type="radio" id="radio" value="" name="packages" onclick="callrest(this.value);"/>
