Display the tool-tip for drop-down option values

Here is my select drop-down box .hbs code, I need to add the tool-tip for content.name (drop-down labels) on mouseover.

{{view Ember.Select contentBinding=entities
                                        optionLabelPath="content.name"
                                        optionValuePath="content.id"
                                        prompt="-- Select --"
                                        valueBinding=entityId }}

content.name it will retreive the name from array object
