ajax option as a function for server side processing

Kirkules

I defined a data function that I'm asigning to the ajax property.

dataFunction(data, callback, settings) {

console.log("draw: " + data.draw + "; order column: " + data.order[0].column + " " + data.order[0].dir + ";");
...
callback({
draw: data.draw,
data: this.leads(), // domData,
recordsTotal: this.leads().length,
recordsFiltered: this.leads().length
});
}

The first time the table is displayed, the dataFunction is called 4 times. If I click on the ordering controls (changes column 0 from asc to desc) it's called at least 2 times. Sometimes with different draw values, sometimes with the same. There's no real ordering I can pattern.

from the console:

draw: 1; order column: 0 asc;
leads.ts:175 draw: 1; order column: 0 asc;
leads.ts:200 did not call setEntities
leads.ts:189 called setEntities
leads.ts:175 draw: 1; order column: 0 asc;
leads.ts:200 did not call setEntities
leads.ts:175 draw: 1; order column: 0 asc;
leads.ts:200 did not call setEntities
leads.ts:175 draw: 2; order column: 0 desc;
leads.ts:175 draw: 1; order column: 0 asc;
leads.ts:200 did not call setEntities
leads.ts:189 called setEntities
leads.ts:175 draw: 2; order column: 1 asc;
leads.ts:200

Can anyone tell me why this function is getting called repeatedly? how to stop it? what I'm doing wrong?

Probably should put up more of your code to see if there is an event handler or something else that is triggering this.

Figured it out in the shower this morning..

The initialization of the datatable control ishandled inside a custom knockout binding and it was being reinitialized on each update.. I removed the update method and only initialize the control once in init: all is well now.

Thanks for the support...

to funny, I made that exact same mistake.
