How to add new DS attributes dynamically in ember-pouch model

[LowBP]

I am working on table, I want to create a single model for multiple tables with different DS attributes. how can i handle this.
ex:
table1 model is column

import {  Model  } from 'ember-pouch';
export default Model.extend({
    abc: DS.attr('string'),
    bcd: DS.attr('number'),
    abcd: DS.attr('date') 
})

The same model column for table2 but DS.attribute is not same as table1
ex:

 import {  Model  } from 'ember-pouch';
 export default Model.extend({
    abc: DS.attr('number'),
    bcd: DS.attr('date'),
    abcd: DS.attr('boolean') 
 })
