We do that of jquery delegate event when we have to bind event on both parent and child then we do it and it works like this, if removes event of both parent and child then use the undelegate event.
```
Syntax
$(selector).delegate(childSelector, event, function)
$(selector).delegate(childSelector, event, data, function)
$(selector).undelegate ()
$(selector).undelegate (selector, event)
$(selector).undelegate (selector, event, function)
```
```
ready function
