Render Function - not executing when defined as a string

[Webauthor]

Hello,

Since very 8.4, render functions defined as a string (to point to an external function) are no longer working.

You can see in this fiddle showing 8.3.  A simple function is defined "renderCell" and specified in the render attribute of the first column in colModel - Rank.

When switching the library to 8.5, we're getting the error below:

Please use this patch for now, it can be included just after loading pqgrid js file.

Code: [Select]

$.paramquery.pqGrid.prototype.callFn = function(cb, ui){
return pq.getFn(cb).call(this, ui);
};
