You're not up to date with the events in this part of the world. Turkey isn't fighting the Daesh. Never has. It's more like "the enemy of my enemy (Kurds, Assad) is my friend (or to be ignored for now)". The Daesh are also pretty much ignoring Turkey.
The only way to have Turkey fight the Daesh if to provide concessions in Syria for Turkey, concessions that aren't feasible as they would further destabilize the region (as neither Iran nor SA will be happy about it) and antagonize Russia.
If not active combat, the Turks are hosting over 3 million of them in refugee camps. In fact I wrote about an article on this months ago. Perhaps you can avail it , please read it. I wrote it over a year ago.
