How to work with dynamically loaded elements in YUI - yui

Question

I'm currently trying to integrate spring mvc app using YUI3. I was able to call Spring Controller with static href in jsp through YUI, but script is not getting invoked when trying to invoke dynamically generated href.
<script src="http://yui.yahooapis.com/3.14.1/build/yui/yui-min.js"></script>
<script>
YUI().use('io-form', 'json','datatable','node','tabview',function(Y) {
Y.all('#nav a').on('click', function (ev) {
ev.preventDefault();
//main.load(ev.target.get('href'), '#content');
var href = ev.target.get('href');
var url = href.substring(0,href.indexOf('#'));
var idw = href.substring(href.indexOf('#')+1,href.length);
Y.io(url, {
method: 'GET',
on: {
complete: function(id, response) {
answer = Y.JSON.parse(response.responseText);
Y.log(answer);
var main = Y.one('#'+idw);
var node = main.all('li');
if(node.size()===0){
Y.Object.each(answer, function(item, index){
main.append("<li id='"+item+"' class='api-list-item class'><a href='/YUI-2-Spring/getContactDetails/"+item+".html#"+item+"'>"+item+"</a></li>");
});
}
}
}
});
});
//To call controller on clickin of dynamic links
Y.all('#api-Types a').on('click', function (ev) {
ev.preventDefault();
//main.load(ev.target.get('href'), '#content');
var href = ev.target.get('href');
var neturl = href.substring(0,href.indexOf('#'));
var studId= href.substring(href.indexOf('#')+1,href.length);
Y.io(neturl, {
method: 'GET',
on: {
complete: function(id, response) {
answer = Y.JSON.parse(response.responseText);
Y.log(answer);
var main = Y.one('#api-everything');
var node = main.all('li');
if(node.size()===0){
Y.Object.each(answer, function(item, index){
main.append("<li id='"+item+"' class='module-class'><a href='/YUI-2-Spring/getPersonalDetails/"+item+"/"+contId+"'</a>"+item+"</li>");
});
}
}
}
});
});
});
</script>
The first script I'm using for calling controller on tabview selection .Based on that I'm creating a list of String with href inside <ul id="api-Types" class="apis modules"></ul> field. In the next script, I'm trying to invoke the generated links, but script is not getting executed.
<div class="yui3-u-1-4">
<div id="docs-sidebar" class="sidebar apidocs">
<div id="api-list">
<h2 class="off-left">APIs</h2>
<div id="api-tabview" class="yui3-tabview-content">
<ul id="nav" class="tabs">
<li class="yui3-tab yui3-widget yui3-tab-selected">Elements</li>
<li class="yui3-tab yui3-widget">Contact Details</li>
<li class="yui3-tab yui3-widget">All</li>
</ul>
<div id="yui3-tabview-panel">
<ul id="api-elements" class="apis classes">
<input type="search" id="api-filter" placeholder="Type to filter APIs">
</ul>
<ul id="api-Types" class="apis modules">
<input type="search" id="api-filter" placeholder="Type to filter APIs"></ul>
<ul id="api-everything" class="apis search">
<input type="search" id="api-filter" placeholder="Type to filter APIs">
<li class="message">
Begin typing in the search box above to see results.
</li>
</ul>
</div>
</div>
</div>
This is the dynamic list that got generated got from viewsource:
<ul id="api-Types" class="apis modules yui3-tab-panel yui3-tab-panel-selected" role="tabpanel" aria-labelledby="yui_3_14_1_1_1389513296688_62">
<input type="search" id="api-filter" placeholder="Type to filter APIs"><li class="api-list-item class">ABC</li><li id="BCD" class="api-list-item class">BCD</li><li id="CDE" class="api-list-item class">CDE</li><li id="DEF" class="api-list-item class">DEF</li><li id="EFG" class="api-list-item class">EFG</li><li id="FGH" class="api-list-item class">FGH</li></ul>
When I'm clicking on the links, instead of invoking the script, my controller is getting invoked through Dispatcher servlet.
Any help will be appreciated.

To bind events on dynamically added element on DOM you should use 'delegate' to bind event instead of 'on'. It will work.
