Bower - social-feed error

I am using Sage 8.4.2, I installed this package via bower install social-feed --save
and it seems everything is ok, in fact i can see the package in my bower.json file

"dependencies": {
"bootstrap-sass": "3.3.6",
"font-awesome": "fontawesome#^4.7.0",
"owl.carousel": "^2.2.1",
"waypoints": "^4.0.1",
"jquery_lazyload": "jquery.lazyload#^1.9.7",
"social-feed": "^0.1.2"

This jQuery plugin needs dependencies javascripts: Codebird.js, doT.js, Moment.js, and I can see them correctly in the bower_components folder.

so I run gulp, but I have this error: doT is not defined.

any idea why?

I tried without bower, enqueueing all the dependencies before the main.js and works well.
But I don’t like this solution, because I need to do download 4 different js.
I would like to use the benefit of bower and load everything in the main.js file.

what I can try to do?

Thank you for your help in this matter.
