Question: I want to programmatically check a checkbox and trigger the checkbox's onchange function

I have tried `("#myCheckbox").click()` but it only checks it and does not call its onchange function

How can I get the onchange function to execute as well?

**edit:**

When the document is ready i need the checkbox checked and its on change function called programatically.

Answer: 
Your change listener needs to be set **before** you trigger the click on the checkbox. The following code works with no issues:

```
$("#myCheckbox").on('change', function(){
   console.log('Change'); 
}).click();

```

Don't understand, it works : <http://jsfiddle.net/FW5Lp/>

```
<input type="checkbox" id="myc">
    <button id='clic'>click</button>

$('#myc').on('change', function(){alert('ca change');});

$('#clic').on('click', function(){$('#myc').trigger('click') });

```
