I have created several elements dynamically in javascript. These are, among others, range inputs. I want on "input change" event to show the value. Each of these inputs have id like 'probabilitate'+number. The number is a global variable, and is incremented on click event of a button.

When I create dynamically these inputs, the input change event does not work anymore. There is a question on stackoverflow, in which the solution is live event, not on event, and it works, partially. The code is:

 $(document).on('change','#probabilitate'+nrBoli, function(){

      //something
  })
The problem is that if the event is triggered on '#probabilitate1' (for example) event, the variable nrBoli works fine inside the function, but if I want to concatenate it with the name for id as parameter (my case, to trigger for each element), nrBoli is unavailable.

You need to use 'class' instead 'id' to get all elements. Using 'id' you get only the first element in the DOM:

Append elements:

var globalProp = 1;

$("#sameContainer").append('<input type="checkbox" id="inputId" class="probabilitate' + globalProp + '"/>');

Set change event:

The change event must be set whenever new elements is appended.

$('.probabilitate' + globalProp).change(function () {
    //do action
})

Example:

var globalProp = 1;

function appendInput(){
    $("#sameContainer").append('<input type="checkbox" id="inputId_a" value="check this" class="probabilitate' + globalProp + '"/>');
    $("#sameContainer").append('<input type="checkbox" id="inputId_b" value="or this" class="probabilitate' + globalProp + '"/>');
    $("#sameContainer").append('<input type="checkbox" id="inputId_c" value="or this" class="probabilitate' + globalProp + '"/>');

    $('.probabilitate' + globalProp).change(function () {
        //do action
    })
};

Hope this helps.
