Hi,

This is workaround which shows issue with listerners like keyup, focus ,blur associated with textfied.
First param of each of these should be field object reference but it is not what i'm getting. But for change event it works fine.
Code:
{
                            xtype: 'textfield',
                            name : 'name',
                            label: 'Name',
                            useClearIcon: true,
                            autoCapitalize : false,
                            listeners  : {
                                keyup: function(field) {
                                    console.log(field,"keyup");
                                },
                                focus: function(field) {
                                    console.log(field,"focus");
                                },
                                change: function(field) { // works fine
                                    console.log(field.getValue(),"change");
                                },
                                blur: function(field) {
                                    console.log(field,"blur");
                                }
                            }
                        }
