How can I access to an HTML control runat server from javascript
<p>I have the following code:</p>

<pre><code>&lt;telerik:GridTemplateColumn DataField="JOB_CODE" 
&lt;EditItemTemplate&gt; 
&lt;input type="text" ID="JOB_CODETextBox" runat="server" 
 value='&lt;%# Eval("JOB_CODE") %&gt;' readonly="readonly" 
 onclick="$('#basic-modal-content').modal({
                                          appendTo:'form', persist: true,
                                          onClose: function (dialog) 
                                                   {
                                                      /*
           I want to assign here a value to the textbox control
           like this: JOB_CODETextBox = 'something...'
           I tried this: 
           $find('&lt;%= JOB_CODETextBox.ClientID %&gt;').value = 'something..'
           but it didn't work!! the find function returns [null]
                                                      */
                                                      $.modal.close();
                                                   }
                                         } );" /&gt;
</code></pre>
