Call a function If any Item is chosen From select box , After Dom update


Call a function If any Item is chosen From select box , After Dom update

Hope this helps The problem you're having is that you're binding the event handler to the specific element that is, according to what you wrote above, is being added and removed from the DOM dynamically based on the return of an AJAX call.
As implied by the other answer that was here originally, you want to instead bind the event handler to the parent of this select element instead. Assuming that the parent is never removed (and if it does, go a level higher), as Benjamin Gruenbaum said, the second parameter of the on method accepts a context-sensitive selector which specifies on which elements to trigger the event, like so:
code :
$(".your_parent_element").on("change", "select.foodselect", function(event) {
    alert("hi");
});

code :
var theValue = $(this).find('option:selected').text();
if ($(this).find('option:selected').val() === 'nonresident') {
    residenceAlert();
}

To fix the issue you can do Your problem is that nothing in IssueCollection variable says it should get updated if self.selectedListItem changes. You have to use computed variable to enable this functionality. Also you should make IssueCollection a property of your model. See below, also check Fiddle.
code :
self.IssueCollection = oj.Collection.extend({
    url: ko.computed( function() { return self.serviceIssueURL + 
          "?q=AccountId="+self.selectedListItem() }),
    model: 'myIssue'
});

should help you out I think I solved the issue by nesting a update-end event handler with the row-select handler. I also remove the update-end handler after the confirmation. Otherwise, I stack up confirmation windows if I don't click cancel. Here is the part of the code I changed.
code :
                map.addLayer(routeFeature);
            on(routeFeature, "load", function(){
                loadTable();
                myFeatureTable.on("row-select", function(evt){
                    routeChange = routeFeature.on("update-end", function(none){
                                            confirmRoute(evt);
                                        });
                  });
              });
            function confirmRoute(evt) {
                var message = "Is this the correct route?\nEntry State: "+
                                evt[0].data.ORIGIN  + "\nRoute Description: " +
                                evt[0].data.ROUTE_DESC + "\nExit State: " +
                                evt[0].data.DESTNATION ;
                if (confirm(message) == true) {
                    document.getElementById('shipment_gisRouteId').value = evt[0].data.ROUTE_ID;
                    document.getElementById('shipment_routeText').value = evt[0].data.ROUTE_DESC;
                    var oldAction = document.getElementById("shipment").action;
                    var url = oldAction.replace("shipment","shipment"+"_saveRoute");
                    document.forms[0].action = url;
                    document.forms[0].submit();
                }
                routeChange.remove();
            }

may help you . If you are using Jquery, you can do that in a simpler way. Of course, don't forget to import the Jquery library.
code :
function showState() {
  if ($("#country option:selected").val() === "australia") {
    $("#state").show()
  }
  else {
    $("#state").hide()
  }
}
$("#country").change(showState)
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<select name="country" id="country" required>
  <option value="" disabled selected="selected" hidden>Country</option>
  <option value="australia" id="australia">Australia</option>
  <option value="england">England</option>
</select><br>
<select name="state" id="state">
  <option>Queensland</option>
  <option>Victoria</option>
</select>
