    <p>I have an ajax call that uses the following code to add some rows to a data table for each record in the response:</p> <pre><code> strAppName = data.Application_Name maintCost = '&lt;input class="maintCostField" appid="' + data.Application_ID + '" type="text" placeholder="$"&gt;'; $('#myReport').dataTable().fnAddData([ strAppName, maintCost, etc, etc ]); </code></pre> <p>I've tried the following selectors/events to catch changes to the text box, but none of them trigger. They are in the document.ready section...</p> <pre><code>$(".maintCostField").bind('change',function () { val = $(this).val(); app = $(this).attr('appid'); alert('Updating app# ' + app + ' with ' + val); }); $(".maintCostField").on('change',function () { val = $(this).val(); app = $(this).attr('appid'); alert('Updating app# ' + app + ' with ' + val); }); </code></pre> <p>(I know this one is deprecated)</p> <pre><code>$(".maintCostField").live('change',function () { val = $(this).val(); app = $(this).attr('appid'); alert('Updating app# ' + app + ' with ' + val); }); </code></pre> <p>and of course this didn't work</p> <pre><code>$(".maintCostField").change(function () { val = $(this).val(); app = $(this).attr('appid'); alert('Updating app# ' + app + ' with ' + val); }); </code></pre> <p>What am I doing wrong? I don't see why it's any different than <a href="https://stackoverflow.com/questions/6658752/jquery-click-event-doesnt-work-on-dynamically-generated-elements">Click event doesn&#39;t work on dynamically generated elements</a> or many others...</p> <p><strong>update*</strong> I added the following to the fnDrawCallback event of the datatable and now it works, only it executes as many times as there are forms on the screen.</p> <pre><code> $(".maintCostField").each(function () { this.addEventListener("change", function () { val = $(this).val(); app = $(this).attr('appid'); alert('Updating app# ' + app + ' with ' + val); }, true); }); </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
