Overide problem

[myavuz]

In this code, I have written 'this.papername' to text value for column label which is define in the object. However, it does no see it, nothing prints in the column name, I should overwrite it for localization so I need it, why it does not reach this.papername?Thanks

Ext.define('Confman.view.AuthorPaperList', {
    extend:'Ext.grid.Panel',
    title: 'Papers',
    id:'authorPaperList',
    papername:'gdfh',
    height:300,
    store: {
        fields: [{name: 'name', type: 'string'}],

    },
    columns: [
              { text: this.papername,  dataIndex: 'name' },
              {
