you can not get HTML Element through id in javascript directly. ASP.net is server side language and Javascript is client side so you need to get CLient ID . Try this ..

$('#<%=rdbrawmtrl.ClientID%>').click(function(){
      // your code here ....
});

You are not able to retrieve value because your ASP.NET RadioButton is rendered like this in browser:-

<tr>
  <td>
     <input name="rdbrawmtrl" id="rdbrawmtrl_0" type="radio" value="Cotton">
     <label for="rdbrawmtrl_0">Cotton</label>
  </td>
</tr>

<tr>
  <td>
     <input name="rdbrawmtrl" id="rdbrawmtrl_1" type="radio" value="Wool">
     <label for="rdbrawmtrl_1">Wool</label>
  </td>
</tr>

As you can see the Id will be generated dynamically for each radio button. You should write a selector on name attribute like this:-

$('input[name="rdbrawmtrl"]').click(function () {
     var value = $(this).val();
     alert(value);
});

Update:

Having a Master Page will not only change the Id dynamically but also the name attribute. You can add a class to your RadioButtonList like this:-

<asp:RadioButtonList ID="rdbrawmtrl" runat="server" Style="margin: 0 4px 8px 0;" 
                      CssClass="clsrdbrawmtrl">

Then you can find the radio buttons present inside it like this:-

$('input[type="radio"]',$('.clsrdbrawmtrl')).click(function () {
     alert($(this).val());
});

I have assumed that ASP renders your radio buttons as below.

$("input[name='rdbrawmtrl']:radio").change(function() {

    var val = $(this).val();
    alert ( val );
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<tr>
  <td>
      <input name="rdbrawmtrl" id="rdbrawmtrl_0" type="radio" value="Cotton" />
     <label for="rdbrawmtrl_0">Cotton</label>
  </td>
</tr>

<tr>
  <td>
      <input name="rdbrawmtrl" id="rdbrawmtrl_1" type="radio" value="Wool" />
     <label for="rdbrawmtrl_1">Wool</label>
  </td>
</tr>

Edit: Based on your comment, try the following.

$("input[id^='ContentPlaceHolder1_rdbrawmtrl']:radio").change(function() {

    var val = $(this).val();
    alert ( val );
});
