AngularJS: Function call in ternary operator conditional check

My HAML file:

%pipes-autocomplete{:model =>"filter.value",:option => "validate_option(filter)" ? "dependant(filter)" : "filter.option"}

My Coffee Script:

  $scope.validate_option =(filter)->
     console.log "called validate_option"
     if filter.hasOwnProperty('option') && filter.option.indexOf('dependant') > -1
       return true
     else
      return false
  $scope.dependant =(cal)->
    return "choosed"

In the ternary operator I'm trying to call the validate_option function defined in my angular controller.But the function is not getting called.Can someone help me with this problem.

As you put it in the question, the ternary operator will consider the string "validate_option(filter)" to be true (just because it is not an empty one).

Instead put the ternary operator inside the string: 

"validate_option(filter) ? dependant(filter) : filter.option"

That way you defer the execution of the ternary operator to when the string is actually evaluated.
