Facebook Custom Audience pixel on SinglePageApplication SPA

Question

I have a SinglePageApplication built with AngularJs. I want too add Facebook Custom Audience tracking pixel globally and update it manually every time user changes page (url). <

Answer 1

I managed to resolve this by loading _fbq object:

and then calling 'PixelInitialized' event every time page changes.

$window._fbq.push(['track', 'PixelInitialized', {}]);

Since then facebook correctly tracks my audiences.
