Ng2-smart-table selectText issue in editor-config for dropdown (Add,Edit)

[vikkikrishna]

Hi...
I have tried using ng2 smart table to display the data but the issue is on dropdown to be displayed with placeholder (used default attribute "selectText" in editor -config) on clicking Add New and Edit Action.
Placeholder not working while clicking the Add New action and Edit action on select field.

///Typescript
this.settings = {
edit: {
editButtonContent: '',
confirmSave: true,
},
delete: {
deleteButtonContent: '',
confirmDelete: true,
},
actions: {
position: 'left',
}, attr: {
class: 'table'
},
add: {
confirmCreate: true,
addButtonContent: 'add new', this: this.checking()
},
columns: {
employeeFirstName: {
title: 'First Name*',

    },
    employeeLastName: {
      title: 'Last Name',
    },
    employeeEmail: {
      title: 'Email*',
      editable: false
    },
    role: {
      title: 'Role*',
      type: 'html',
      valuePrepareFunction: (cell, row, companyList) => {

        // this.placeholder();
        let bn = this.userRoleList.find(x => x.value === cell);
        if (bn) {
          return bn.title;
        }
        else {

          return cell;
        }
      },
      editor: {
        type: 'list',
        config: {

          selectText: 'Select',
          list: this.userRoleList

        }
      }
    },
    ageGroup: {
      title: 'Age Group*',
      type: 'html',
      valuePrepareFunction: (cell, row, companyList) => {
        let bn = this.ageGroupList.find(x => x.value === cell);
        if (bn) {
          return bn.title;
        }
        else {
          return cell;
        }
      },

      editor: {
        type: 'list',

        config: {
          placeholder: 'hello',
          selectText: 'Select ID',

        }
      }
    },

      type: 'html',
      valuePrepareFunction: (cell, row, companyList) => {
        let bn = this.employerExpList.find(x => x.value === cell);
        if (bn) {
          return bn.title;
        }
        else {
          return cell;
        }
      },
      editor: {
        type: 'list',
        config: {
          selectText: 'Select',

          list: this.genderList

        }
      }
    }

  },
};
