Jquery data-role collapsible events aren't being captured in Jquery Mobile

问题

Could anybody please let me know why the following code isn't working when i am using with Jquery mobile JS

http://jsfiddle.net/znz17ctm/7/ This is my code

<div role="main" class="ui-content oms-content" id="dd">
    <div class="myactivelabelsWrap" id="result"></div>
</div>



var response = {
  "Restaurants": [{
    "RestrntArea": "Haii",
    "cust_loc_id": "374"
  }, {
    "RestrntArea": "rerrrwe",
    "cust_loc_id": "373"
  }]
}
showLabels();

function showLabels() {
  //$("#result").html("");
  var favoriteresultag = '';
  for (var i = 0; i < response.Restaurants.length; i++) {
    var name = response.Restaurants[i].RestrntArea;
    if (name) {
      favoriteresultag +=
        '<div data-role="collapsible" data-inset="false" class="my-collaspible"><h3>' +
        name +
        ' <a class="icon-pencil-1 labelEditIcon "></a></h3></div>';
    }
  }
  $("#result").append(favoriteresultag).trigger("create");
}
$(document).ready(function() {
  $('.my-collaspible').bind('expand', function() {
    alert('Expanded');
  });
  $('.my-collaspible').bind('collapse', function() {
    alert('Collapsed');
  });
});

Why the collapse and expand even'ts are being captured ??

Instead of document ready i tried with al the page events of mobile . But no luck .

From your fiddle I can't tell which version of jQM you are using. You have checked version 1.3 but then added the 1.4 css. Assumin version 1.4, I have updated your fiddle:

FIDDLE

Basically, you need to use event delegation to attach the events because the collapsibles do not exist at the time of the bind. Also the event names are actually collapsibleexpand and collapsiblecollapse.

So use on() instead of bind() by handling the event on the parent div and delegating it to all items with class my-collapsible that exist now or added dynamically:

$("#result").on('collapsibleexpand', '.my-collaspible', function () {
    alert('Expanded');
});

$("#result").on('collapsiblecollapse', '.my-collaspible', function () {
    alert('Collapsed');
});
