title: jQuery event bubbling issue with dynamic data()
body: <p>I have a bit of jQuery, but put it here a simplified version to better identify any possible glitch. I provided some comments inline the code to better highlight my attempts and also the problem. Please find my comment inline the codes.</p>
  
  <p>My problem is the "Clear" button, clears out any input previously clicked, while it should only clear the current active input. Smells like event bubbling issue, but I couldn't identify it by now, so your help is very much appreciated.</p>
  
  <p>The workflow is like this:</p>
  
  <ol>
  <li><p>I click input.trigger (<code>input[name="a"]</code>) inside .container</p></li>
  <li><p>div#popup is popped out/ launched</p></li>
  <li><p>I click a button "Clear" inside the #popup, it does clear the <code>input[name="a"]</code>. I do a "revert" to put back the value, good so far, if some default value is there, it reverts (this part is not included in the code, because it is not the main problem, if the following is solved). Close it. So input "a" was cleared, but later reverted with its default value via stored data-default.</p></li>
  <li><p>Good, so far.</p></li>
  <li><p>I click another input.trigger (<code>input[name="b"]</code>), #popup launched, more actions.. good, but ....</p></li>
  <li><p>I click "Clear" button, it clears input "a" and "b", while it is expected to clear only current <code>input.trigger[name="b"]</code> (not with previous inputs, "a").</p></li>
  </ol>
  
  <p>The solution <a href="https://stackoverflow.com/questions/9153501/how-do-you-stop-children-from-propagating-an-event-triggered-by-a-live-delegate">here</a> doesn't help yet.</p>
  
  <pre><code>$('.container').on('focus', 'input.trigger', function(e) {
     e.preventDefault();
     // First fix attempt, no use
     // https://stackoverflow.com/questions/9153501/how-do-you-stop-children-from-propagating-an-event-triggered-by-a-live-delegate
     // Trying to solve problem with event bubbling, but no use
     if (e.target != this){ 
       return true; 
     }
     var input = $(this);
     // somewhere added a class focused on input focused, please ignore.
     // we add blur here to make any button or input inside popup clickable.
     $('input:not(.focused)').blur();
  
    // Added dynamic data("popup") based on input name (a, b, c, d)
    $("#popup").data("popup", this.name).css({
      left: "20px",
      top: input.offset().top + 24 + "px"
    })
    // Second fix attempt, no use
    .stop(true, true)
    .show('slow', function () {
      var currentPopup = $(this),
        popupName = currentPopup.data("popup"),
        // Trying to get input/trigger name from data "popup" per clicked input name.
        // I tried putting this after `var input = $(this);` above but put it here later
        // thinking it should solve the problem, but alas not.
        theinput = $('input[name="' + popupName + '"]'),
        // Used for other dynamic interaction with some classes (.a_popup, .b_popup, etc).
        popupid = theinput.data('popupid');
  
      currentPopup.on('click', '.clear', function(e) {
        // Third fix attempt, no use
        e.stopPropagation();
        // The problem is here:
        // The button clears out any previous (opened) input.trigger,
        // while it should only clears the input with name == current popupName
  
        // Why this also bubbles to previously opened input.trigger "popupid"
        console.log(popupid); 
  
        theinput.val("");
      });
      // More buttons here: Revert and Close. But once the "Clear" button issue is solved, this is no issue. So excluded.
    });
   })
  .on('blur', 'input.trigger', function (e) {
    e.preventDefault(); // no use
    var hidden = $("#popup"),
      popupName = this.name;
    if (hidden.data("popup") === popupName) {
      hidden.hide().removeData("popup");
    }
  });

  <p>I hope I can make myself clear, but if not I will update if anything I missed from the simplified code above.
  Thanks for any hint to spot the actual problem.</p>
  
  <p>UPDATE:
  <code>$('.container').off('input.trigger');</code> is attached to Close button.</p>
