I have to do something like this: http://ift.tt/S5qKzJ

The task is simple: assign an id to an input tag in html and get the value through javascript. I have done the SAME thing on my application (the code is very large, so i will not post it here!), but it does not work. I have something like:

321    <div id="old_pw_sp" class="col-xs-7">
322        <input type="password" id="current_password"/>
323    </div>

and the same js of the fiddle (whit right names of the div):

149     var crr_pw = document.getElementById("current_password").value;

but I keep gettin the error:

TypeError: document.getElementById(...) is null

If i analyze the input tag with firefox analyzer I get this:

<div id="old_pw_sp" class="col-xs-7">
    <input type="password">
</div>

The id is not there, but I cannot figure out why. Can someone please help me?
