beforeRemove callback called for each row inside datatable

[gentunian]

I'm using tabular and a template for a column that displays actions buttons:

Tabular is initialized with the last column as a template:

{
      tmpl: Meteor.isClient && Template.actionCell,
      sWidth: "20px",
      sClass: "td-center",
}

Template is something like this:

<template name="actionCell">
        <div class="btn-group" role="group">
            <button id="{{this._id}}" type="button" class="btn btn-xs btn-primary" data-toggle="modal" data-target="#editEntryDialog"><i class="fa fa-edit"></i>
            </button>
            {{# quickRemoveButton collection="MyCollection" _id=this._id onError=onError onSuccess=onSuccess beforeRemove=beforeRemove class="btn btn-xs btn-danger"}}
            <i class="fa fa-trash"></i>
            {{/quickRemoveButton}}
        </div>
</template>

I wrote a simple helper to test the functionality:

  Template.actionCell.helpers({
    beforeRemove: function() {
      alert('a dialog');
    }
  });

When the datatable loads, the alert dialog gets invoked. I think this is due the case that the content block is rendered and so the helper is being called.

Is it possible to use the template as a content block and make use of callbacks?

Note: I'm sorry for the editions, I had a lot of troubles with my touchpad.

Since beforeRemove expects a function, your helper function needs to return a function. It can be confusing, but it makes sense if you think about it hard enough. :)

Template.actionCell.helpers({
    beforeRemove: function() {
      return function () { alert('a dialog'); }
    }
});

Thanks for the reply @aldeed. Didn't note that.
