You should NOT delete this on the template itself, but on the template used as an instance on a window YES.  
I encourage to start with indirect tag bindings first to understand the concept and the jump to user defined parameters.

Also it looks like your are doing a bad binding type at the template, when you are using user defined you should you **property binding** , like this:

But I think is totally unnecessary in this case since I think your missing a step somewhere.
