Ember-models-table addon throws ember warn error while trying to use 'routeName' property

Am using ember-models-table to display table in my applicaiton. The table is great for sorting , pagination etc, but am trying to route from specific row to different page based on the id. it has mentioned in its example to use 'routeName' But when I use it throws the following error:

"Assertion Failed: When calling warn you must provide an options hash as the third parameter. options should include an id property."

My .js coding :

columns:[   
        {
          "propertyName": "firstName",
          "title":"First Name",
          "routeName":"/#/profile/_id"
},

and so on

Thanks for your help.
