How to do drag and drop

[ghost]

Hi All,

I am using astrolabe to automate my angular js webpage.
i am using the below code for the drag and drop, and its not working.
one question is how do we call actions.dragAndDrop from the page object.
please help me to resolve.

Thanks in advance.

drag1: { get: function() { return this.findElement(this.by.repeater('unmapped in unmappedFields').row(2)); } },
drop1: { get: function() { return this.findElement(this.by.id('targetList')); } },

addClientObject: { value: function(objname) {

    var page = this;

    page.go();
    page.addcliobjbtn.click();
    page.cobjname.sendKeys(objname);
    browser.actions().dragAndDrop(page.drag1, page.drop1).perform();
    page.objsave.click();

}
