on() method does not work as live()

I change some methods from $(selector).live('click', function(){}); to $(selector).on('click', function(){}); .

At first it seems to work exactly the same. But when I insert new html on the DOM, the new elements inserted with the same selector, they aren't catch by $(selector).on('click', function(){}); and before they were catch by the live() method.

why? I'm missing something?

.on takes a different set of parameters compared to .live. You can't just replace one with the other (and $(selector).on.live doesn't make sense).

The correct syntax is:

$(document).on('click', selector, function(){});

This will bind to all elements that match selector no matter when they are added to the DOM.

Note:

Instead of document, you can use a parent of the element(s), as long as that parent stays in the DOM.

For example:

<div id="myDiv">
    <p>Hello World</p>
    <p>Hello World</p>
</div>

Then you can do:

$('#myDiv').on('click', 'p', function(){});

That click event will fire for all <p> tags added to #myDiv.

Note:

$(selector).on('click', function(){})

is the same as doing

$(selector).bind('click', function(){})

(jQuery 1.7.1 suggests using .on instead of .bind)
