Trigger jquery function on input when clicking other input

Question

I'm creating a dinamically added input form. I want to make it so when an input loses the focus, its value get .00 appended to it. So far I tried this:

$(".money-input").on("click", function(e) {
  e.stopPropagation();
});

$(document).on("click", function (e) {
  $(".money-input").each(function() {
    var valTemp = $(this).val();
    if ((valTemp.indexOf(".00") < 0) && (valTemp != "")) {
      valTemp += ".00";
      $(this).val(valTemp);
    }
  });
});

My problem is, it only works when I click on other divs but inputs. Additionally what I also want to achieve is when I edited something on one input then switch focus to other input, the previous input value got appended by .00.

Any help appreciated! :)

Use

$(".money-input").live('blur', function() {
    var valTemp = $(this).val();
    if ((valTemp.indexOf(".00") < 0) && (valTemp != "")) {
        valTemp += ".00";
        $(this).val(valTemp);
    }
});

blur is your 'lost-focus' event. With using live it will attach this event to elements that exists now and in the future (since you are dynamically adding a form).

The requested behavior is odd...use the step attribute instead:

<input type='number' step='01'>

The minimum requirements to have a floating point value in an input is to have: type="number" and step attributes. In the following Demo there are 3 forms with 2 inputs each for a total of 6 inputs.

The first 2 inputs have no step attribute.
The second pair are dynamically created. The first input has no step attribute whilst the second one does.
The last pair of inputs have the step attribute.

I modified the styles so when an input has the step attribute, its borders are red dashed lines. It's not necessary to do this, it's just for demonstration purposes.
There is a jQuery on event handler registered on 2 events, one is blur event and the other is the change event. These events trigger the same handler which will set the step attribute to an input upon the triggering of either change or blur events.

Demo

$('#form1').append("<input id='i2' class='money' type='number' value='0.00'>").append("<input id='i3' class='money' type='number' value='0.00' step='.01'>");

$('.money').on('blur change', function(e) {
  if ($(this).val() > 0) {
    $(this).attr('step', '.01');
  }
});

input[step*=".01"] {
  border: 1px dashed red
}

<form id='form0'>
  <input id='i0' class='money' type='number' value='0.00'>
  <input id='i1' class='money' type='number' value='0.00'>
</form>

<form id='form1'></form>


<form id='form2'>
  <input id='i4' class='money' type='number' value='0.00' step='.01'>
  <input id='i5' class='money' type='number' value='0.00' step='.01'>
</form>
