Openlayers-3 Force a map refresh

I've finally found a solution to refresh a layer on openlayers 3.

You have to update params of the layer source like this:

var source = yourLayer.getSource();
var params = source.getParams();
params.t = new Date().getMilliseconds();
source.updateParams(params);

To solve the issue just use

this.map.updateSize();

I believe you need to force your layer's source to update, you can do so by calling the changed function on it:

yourLayer.getSource().changed();
