javascript - create dynamically buttons to show dialog -

i have button (create) , when it's clicked, creates new button (change coordinates) should able open dialog when it's clicked.

first of created body of dialog window, created via javascript, how looks in html:

<div id="dialog-form" title="change coordinates">   <p class="validatetips">both fields required.</p>   <form>     <fieldset>     <label for="lon">longitude (decimal)</label>     <input type="text" name="lon" id="lon" value="" class="text ui-widget-content ui-corner-all">     <label for="lat">latitude (decimal)</label>     <input type="text" name="lat" id="lat" value="" class="text ui-widget-content ui-corner-all">      <input type="submit" tabindex="-1" style="position:absolute; top:-1000px">     </fieldset>   </form> </div> 

now when create button clicked crate new button able open dialog:

$( "#create" ).button().on( "click", function() {     var btn = document.createelement("button");     btn.id = "change_coord";     var t = document.createtextnode("change coordinates");     btn.appendchild(t);     document.body.appendchild(btn); }); 

and how dialog looks like:

dialog = $( "#dialog-form" ).dialog({           autoopen: false,           height: 300,           width: 350,           modal: true,           buttons:{                 "create account": adduser,                 cancel: function(){                     dialog.dialog( "close" );                 }           },           close: function(){                 form[ 0 ].reset();                 allfields.removeclass( "ui-state-error" );           } }); 

weird works when i'm creating body of dialog , button open in

$(function() { .... }); 

but when i'm dynamically creating button open dialog doesn't work @ all.
here fiddle show problem.

per charlietfl, correct "live" has been deprecated, still remains common solution problem. other method i've used, works is:

$(document).on("mouseenter","#lstmfmenu", function() { 

however, cannot jquery work against dynamically loaded html using $("#selector").on(), must use $(document).on statement shown above.

thanks.
