Itemchanged event in Ext JS

My team is migrating an application which is in Powerbuilder to Ext JS 5.1.

In Powerbuilder, there is an event "itemchanged" which will be invoked whenever a field is modified and loses focus.

When we are migrating to Ext JS, we have mapped the functionalities in this event to blur event of the fields.

Blur event gets fired everytime the field loses focus irrespective of whether or not the value in the field was modified.

So, we mapped these functionalities to change event in Ext JS. Now, the issue is change event gets fired as soon as user starts typing

i.e. for each character entered, change event gets fired which again does not work for some scenarios.

Is there any event in Ext JS which can work similar to "itemchanged" event of PowerBuilder ?

Thanks,

Roger
