javascript - jquery function not catching dynamically generated id -


i have table rows generated ajax query response like:

var inp = '<input id="new_po_qty" style="text-align:center" type="text" value="1">'; $('<tr id="new_po_item_row">').html('<td style="text-align:center">' + sku_id + '</td><td style="text-align:center">' + inp  + '</td><td id="new_po_cp" style="text-align:center">' + cost_price  + '</td><td id="new_po_total_cp" style="text-align:center">' + cost_price  + '</td>').appendto('#new_po_body');

now wrote jquery function catch changes on inp variable in table row. jquery function not catching changes in input box.

jquery function:

$('#new_po_qty').on('change paste', function(){     alert('changes made.');     $.niftynoty({         type:"primary",icon:"",title:"start adding products.",container:"floating",timer:5000     }); });

what doing wrong function?

use event delegation:

$(document).on('change paste', '#new_po_qty', function(){     alert('changes made.');     $.niftynoty({         type:"primary",icon:"",title:"start adding products.",container:"floating",timer:5000     }); });

see jquery .on() docs.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
