how to add event listener for a item like select field in sencha touch

[raju0574]

hi all,
i have one item like this

items:[{ xtype: 'selectfield',
						id:'sector',
                        name : 'mode',
                        label: 'Sector',
                        valueField : 'mode',
                        displayField : 'title', 
                        store : sectorStore,						
						}]

Now if i want to add a listener to that item what i have to do.
whenever change is made in that item i wan to perform some action for that how can we do?

The API describes the events for this type of input field.

Have you checked it?

If you check the API there is a "change" event that is fired just before the value is changed



change( Ext.form.Text this, Mixed newValue, Mixed oldValue )
Fires just before the field blurs if the field value has changed.
Parameters

• this : Ext.form.TextThis field
  
• newValue : MixedThe new value
  
• oldValue : MixedThe original value
